I don't know if this is the correct forum section to put this under, but anyway...

At my school, there is a D&D Club. It started out really, really fun, but then our first DM left and so we had to quickly make a new campaign and get a new DM. Really quickly, two or three people left the new campaign, and a lot of us are considering leaving. I don't know if I should leave the campaign. On one hand, it is one of the few social interactions I have been having with people my age lately. On the other hand, the campaign just isn't as fun as it was before our first DM left. I feel like I should leave, but there are two things that are stopping me. The first thing is I feel like I am one of the only things keeping the campaign together. Often times, I am the person who gets us focused about the campaign, and a lot of times I am the only reason we even meet for club. The second thing is I haven't told my family that it isn't as fun anymore. As much as they try to make me think that everything is not stressful, it feels like every day something stressful happens. I didn't say anything about the campaign becoming less fun because I didn't want to add to that. If I tell them now, about three weeks after this first started happening, I don't know how they'll react to me not telling them. I don't know if I should leave the campaign or wait until the end of the school year, which is relatively soon. Thanks to anyone who responds to this.

I think you should leave, if you're not having fun anymore. No D&D is better than bad D&D. You should probably also tell your parents, but you should say that you were nervous about it. Trying to hide it from them will only make things worse if and when they realize it. You can tell the other players that it's stressful for you and no longer fun. They should understand, and if they don't, they're not the people you should play with, anyway. I hope you manage to figure it out.

I find that gaming clubs work better when there's a variety of activities.  If you want to keep the club and lose the campaign get everyone together and see if there's something else they'd rather play.  If you're this invested and not having fun they probably aren't either.   

It depends a bit on where you want this to go in the long run. From your post, I get the idea that if you leave there won't be a D&D club anymore. Now, it's certainly not on you to help the club survive if you don't want to - that's not your responsibility. However, if you'd like there to be one next year and hopefully be more enjoyable, that probably won't happen if you don't stick it out.

So if it's not worth the trouble, sure, walk away. Explain to the DM and other players you're not enjoying yourself, explain to your parents what happened and that after a few weeks of seeing how it goes you'd just rather spend your time some other way, and go do something else that's more fun. By all means, there's nothing wrong with that.

However, if you're hoping for an improvement and are willing to put in a little effort, maybe try to figure out what went wrong and how it might be fixed. Did the new DM have to take over the old campaign, or did they create a new one? How happy was the new one about becoming DM in the first place? Do people have problems with the new DM's style, and if so can they change a few things to make it better? Is it more about several other players having left and the remaining ones aren't as fun to play with? 

While it’s great that you feel a degree of responsibility for keeping the club together, you shouldn’t try to take on that whole burden alone. If everyone is depending on you, and that level of responsibility is causing you stress, you should probably respectfully back away. D&D should be fun and should relieve stress, not create it. 
Another option could be you taking over the DM role. If you’re the one one most invested in the game, and keeping the club together, that could be a fit.

Or maybe get together outside of school (if you can) with the others who have left the group. Try to get the original group, from when you did enjoy it, back together.

Leave. Maybe talk to some of the other people who left and see why they left and maybe start a new group with them?

I'd suggest to leave early and not wait to long.

Had a similar situation in a online campaign, the first one me and my GF took part in. After the first session we immideatley felt, that the DMs style of running the game was not just our thing and so did alle the other 3 players (although we had filled out questinoairs what we like and dislike and so on). Two experienced online players left immediately after session 1 leaving 3 inexperienced online players with the DM, who quickly found 2 or 3 new players. After the next session, again 1 player left. At that point 3 players had left without giving the DM any reason why.
For another 3 or 4 sessions we (my GF and I) always discussed at the end "this was not fun, but let's wait and maybe it gets better..." and we (whole group) asked the DM for more RP and less streamlined play (quest -> fight -> next quest -> fight, without ever really getting into RP and more background) which he agreed to do. Then another player left and was replaced.

After session 6, just after the latest new player had joinded, my GF, a third player that started with us and I wrote a longe explanation to the DM that our expecations in the game just differ and we weren't having the fun that we hoped for and so on. We made several explanations and even apologize several times that we had the wrong expectations (despite making them clear in the pre-campagin discussions). We've never heard of him again, he just blocked us everywhere immediately (Roll20, Discord...). 

If we just had quit this immediately after the first session and listened to our guts, we could've avoided all this. Instead we just didn't have fun for 6 weeks in a row and spend ~20h ingame + several hours of writing backstories and so on and the time just feels wasted.

Lessons learned: if it is not fun, immediately say so and discuss within the group and the DM. If it still is no fun, quit before you waste to much time. As Thauraeln_The_Bold said "No D&D is better than bad D&D". And what is good or bad depends on what you like. People just like differents styles of DnD or Pen&Paper in general. You just need to find a group and sytle that fits yours.

You mentioned this is a school club.  Is there a teacher or other staff person assigned to the club?  Have you tried talking to them?   Can you be more specific about what isn't fun and why some folks have left?  Leaving may be your best option, but more details might help us see if there are other alternatives that could improve things for you and for others.

My initial reaction when someone asks the question is: yes. Before I read/see/hear any details. When you have got to a point asking, "Should I stop playing in this campaign?" it means you probably should. You'd not be asking yourself this under normal circumstances of D&D.

In terms of your specific case, we can't help unless we know why it isn't fun anymore -- what the DM is doing that is making it not be fun. I think the other suggestion which is that you could offer to DM, might work well. You seem like the "driving force" behind this anyway, and that is what a DM usually is. Players generally just have to show up. Maybe the new DM would be happy to show up but doesn't want to be the "driver." That's OK. Everyone has to find his or her own niche.

Since a lot of you are asking why it isn't as fun anymore...

Part of it is that the campaign isn't really my kind of campaign. And the campaign doesn't work super well for the character I made, but I like that character and don't want to get rid of her. Also, that character got imprisoned, and the DM is making it nearly impossible to escape. It's been a few sessions and I still have not been able to get my character out, and none of the other characters are even trying to help her escape. This leaves me just sitting there while everyone else is doing combat and roleplay and my character isn't doing much at all. I guess the last thing is when we changed who was the DM and what campaign we were doing, a lot of people left, including my best friend. She was the main reason I joined that specific campaign in the first place, and it just doesn't feel the same without her. Again, thanks to everyone who replied to this forum.

Have you tried talking with the group and the new DM constructively about what isn't working for you, and what everybody's expectations for the game are? If it's a newish DM, they're probably trying their best and just haven't realized that that's a conversation they need to have. If they're an experienced DM they have probably had that conversation before and just didn't realize that this group wasn't enjoying the game. 

If they're just a bad DM and are not open to constructive (emphasis; CONSTRUCTIVE) criticism, and if they've been petty and un-fun about it? Then yeah drop that campaign like it's hot.

Bit of a dick move on the other players' part there, and something the DM should be more sensitive to as well. It's supposed to be a cooperative game, leaving someone out of the fun isn't nice. But it's certainly something you can bring up out of game. If everyone's receptive to your concerns, maybe it can be solved. If you feel they're not taking your enjoyment seriously, you can always walk away after giving it that second chance.  

Eeeehhhh.... getting imprisoned and LEFT there is a pretty big dickish move, imho. I can't even fathom why a group would want to leave a companion there, if not some kind of bullying. 

Yeah, abandoning a character in jail is a pretty big red flag, especially if the DM doesn't have anything for you to do while in jail... even if escape is impossible, if you're coming to the table every week there should be something your character can be doing in there... meeting an interesting prisoner for a plot hook, finding  secret room with something of value hidden inside, anything but just saying "you're in jail now" and shooting down any escape attempts. 

Even if you were being a disruptive murderhobo whose character probably should be in jail, punishing you In Character instead of having a discussion out of game to resolve the conflict is a bad sign. Not that I'm accusing you of such a thing, but just saying... even if you're at fault for your playstyle and this is intended as punishment for it, that's still a bad sign.

I'd recommend getting in contact with the people that left... especially since one of them is your best friend. I know it can be hard to arrange meetups these days outside of places like school, but maybe you could all get together on discord or something and play virtually. It's a little jarring at first but you get used to it.

Based on the additional info - yes, leave the campaign.

I agree with Transmorpher -- get in touch with the old people you liked playing with and play with them. You be the DM if no one else wants to. It sounds like you are pretty motivated and DMing can be super rewarding.

leave those bums, you got stuck, cause they got some drama on you.   You likely the last to know whats going on.  

It sounds like they are passive-aggressively trying to push you out. You don’t need that kind of hassle in your life. Find a new group, or maybe convince some other, non D&D, friends to start playing.

I believe you should leave for the following reasons:

1. The DM basically makes it so that you can't do anything.

2. If you legitimately ask yourself if you should leave a campaign, the answer is probably yes.

3. Why should you play if it is stressful and not fun?

But remember, the choice is up to you.

If you are not enjoying the campaign, then you should leave for sure.  All that will happen by you staying and forcing yourself to go when you don't want to is that you will lose interest altogether and burn yourself out.

It's okay to take a break.  Don't feel like you have to keep doing it if you're not enjoying it.

If you want the group to continue, though, and you feel like you could maybe do better, then consider taking to your teacher or person who organises the club and see if you could DM.  

I would also say that you should be honest with your parents about not enjoying it anymore if you want to leave and you're only staying because you're worried about telling them. It might seem like it's a difficult to do, but it's always best to be honest about stuff like that because bottling it up and not being honest about how you feel will only make it worse.  

I'm sure you found that totally condescending, so I will shut up now, but the short of it is, if you're not enjoying the campaign any more for whatever reason and you want to leave, then that is what you should do.
