I think there is already great advice in the comments.

This is my two cents.

Iterate and find a way to be comfortable with yourself, perhaps (re)try different things you used to like or try new things you like. If possible in a communal setting (for instance a introduction course in ...). It can be anything from learning a language to a artisan craft.

Mostly look for community you mention you like gaming, there are a lot of gaming related communities out there that are very welcoming!

Also try to go out of your way to leave your comfort zone, this will push you into situations that you are not getting into right now and that may lead to new opportunities.
