I found some local boardgames clubs and knitting clubs that are quite chill :) [and most people playing board games are either not neurotypical or introverted, so it’s a good place to start having minimal interaction]

On a similar note, being social is a skill we learn over time. Usually, while we are teenagers, we do a lot of social faux pas because we haven’t learned yet how to interact. Since you say you spend a lot of time in your room, it’s normal that it would take you a little training before becoming more of a social butterfly. Don’t be discouraged!
