I'm not gonna act like things aren't in a sorry ass state, and I don't know how your situation compares to mine, but what helped for me was just going on a goddamn walk.
For the last 3 years, almost every day I've went on an hour or two long walk, putting a podcast on and just seeing what I lived near, and I've been living in fairly car centric towns. I walk about 5 km a day, Grabbing a snack or a drink if I pass by the dollar store.
Has it gotten me laid? No, but I'm a fuckton happier even when my life has objectively gotten worse. You see things, like flyers for shows for local bands playing, I didn't go to those, but was tempted.
If you don't live in a crime heavy area, I highly recommend it, it does actually make you more sociable, as someone who was and still is very shy. Just see what's in walking distance and make it a routine, you don't have to have a specific time, just see if it's nice out.
