Teenager looking for a game (Beginner)

Hi! I'm >15 (don't feel comfortable saying my age exactly but between 12-15) looking for some people to play with. I personally have never played but I have a basic idea of how it is played/done. I can't really do paid because im broke and don't have the funds to. I'd preferably like to do it via discord (Nixen#0233) and w/ cameras or mics just so I know I'm not playing with weirdos. I am free on most Saturdays and Sundays, (BST or England time zone) but will always try to give a heads-up if I am busy for whatever reason. 

I'm new and want to play a basic campaign to know how the game really works I will be available if you want to play

I'm also new and looking for something simple haha. Would totally be down to give it a try.

I am a fairly new player with rather basic understandings and concepts. I am also a young person (Age will not be shared other than I am between 12-25.) I won't be on all the time, but I will be happy to play! (P.s. I have the monsternomicon v3.5. I would be happy to share some knowledge.)
