I just try to not worry about it, it's in the past and doesn't really matter. Nobody really cares about your own past in my experience. 22-23 is kind of when I started to have more experience with stuff and came out of my shell with stuff like relationships and having a decent social life. Before that I sort of let anxiety and my poor self image get to me and keep me from having fun.
My current situation sort of sucks, social life is not great- I just talk to some people at the gym and that's about it. I just try to take it for what it is i guess. I have other shit to worry about now, so maybe my social life will be better a few months from now after I sort things out. For now I'm just trying to enjoy it for what it is I guess.
