sounds like a change of tact and scenery is needed - you've rooted yourself into the mindset/rut that nothing is worth probably 'cause you've been sat in this situation for so long. You mention people being closed off but yet lots of people going out. Have you reached out to any of them at all? Joined any of said outings?
If that doesn't seem to be working or seem feasible, do you/have you engaged in online spaces at all? If not, it might be worth taking the plunge and seeing what is out there to help scratch that itch for socialising.
Otherwise, maybe try to redirect that energy into something like a new hobby or even new way of doing the things you already are. Not to shoehorn in stuff from here specifically, but an example might be our Game-Along we do in the Video Games section. It's just playing games but with a theme/twist. Heck, a lot of games I've revisited and had a nice refreshing moment playing by doing things like challenge runs, randomisers and archipelagos.
It seems a bit like right now your situation is a tough mountain to climb and you're viewing it as such - try to break it down into smaller steps/points of progression.
I guess a TLDR is: try to do something, however small, to break the routine/cycle you are in right now. That's the biggest cause of everything going on.
An actual response to the thread - just kinda tired tbh!!!! Exhausted even!
