Your drawings are pretty good, you could set up a booth selling some prints of xyz characters for more practice at conventions. You could also join a cosplay group for some series you like.
>Anxious
Could be an underlying issue like ADHD, but know that if you're attractive to women, but not in a masculine way (like Justin Beiber, Harry Potter, Kpop) less-attractive dudes WILL shit on you in an attempt to get laid or boost their social status, particularly when there are women around or in a social hierarchy. Lacking muscle or poor posture will trigger some abuse from animalistic people, if you're around them.
So some anxiety could stem from being around dudes that aren't chill and are hypercompetitive. Something like tennis or badminton could have you around chill people and build social skills.
