Lack of motivation

I’m 22 right now and recently have been having a really hard time finding motivation for anything. I have anxiety and have trouble really talking to new people but really want to make more friends because I don’t have very many and have just lost the motivation to keep trying. Even going to the gym sometimes I end up just sitting inside and doing nothing all day. There’s a lot more I can mention but if anyone has any advice it would be greatly appreciated.
