Beginner looking to join and play a oneshot

Just gonna say this first to save time for those who may comment they'd invite me for a fee or smth like that, ntyyyy I am as broke as can be lol

I'm looking for a group that would invite me to a oneshot since I don't really have the schedule open for a proper campaign that would take me being consistent in showing up. I unfortunately, like many of us, have a busy schedule. I've only ever played D&D once which was 5E 2014 and in Highschool. I do understand the basic rules and how to play for the most part so it shouldn't just be a constant stream of "How does this work?" "Can I do this?" and other stuff like that, but I am still new and obviously won't know everything so.. I guess just be patient.. The only thing is I... Am not great with talking... Especially to newer people.. I just have really bad social anxiety and the one time I tried using a mic I ended up just going "Hi.." "Yeah.." Basically super awkward and one or two word responses because I completely froze up.. So if you could be patient then that would be best..

I'll put a small about myself here just so you can have a feel for who I am and stuff like that
