I've tried board games and table tennis groups, it's at least something. I just found no interest there. I understand your point, for me it isn't easy to show up to something without a real interest or knowing someone. There's more to it than just deciding to go. I have to somehow get out of the door and show up, I'm not a very social person.
Contradictory I know. Until a year ago I was happy alone and never had a friend in teenage+ life, but finding someone I actually liked taught me people can be good.
