I felt (and feel) the same way. Honestly, what helped me a lot was just kinda participating. For a few months, I just said yes to everything. Every invitation, every event, every person asking for help, etc. Even if I really didnt feel like it, it got me out doing things, and that beats sitting around at home doing nothing any day.

I don't want to say it gave me any meaning, I get that elsewhere, but I realized how much I was holding myself back and was a lot happier for it.
