I’m the same age as you, I’m also not super outgoing, so I say: give it time. I was in a bad place after every break up I had and when I rushed things, after a breakup in 2017, it only made it worse. I went out, got drunk and eventually fucking cried. How ridiculous is that?

Until I noticed it was doing me no good, so I decided I would chill at home and that it would eventually pass, because everything fucking passes. Well, it did, and life continued, as opposed to think it was gonna end after the breakup.

Time does wonders. Therapy and getting to know yourself are also great.
