How have you copped with being alone?

I'm in my late twenties and I really don't know if I can get into a relationship or make friends anytime soon. What have anyone in this situation done to cope, because of the years this has been happening, my anxiety came back in a big way and I've grown unable to focus very long on things that I like without stressing out. I'm also very dopamine starved it seems, I'm unable to focus unless I quickly cycle between work and then a reward like games. Sometimes I can enter hyper focus but it still wears at my psyche like if I wasn't taking breaks. It might actually be a bad thing for me to focus that long.

I really think its the isolation. I can't even clean my room except for glaringly bad things like trash piling up, but my house is full of dust.

How could I go about coping so I stop loosing my mind? I would be happy if just the anxiety stopped, and if I could focus on working towards my future for long periods. I thought about dating/making friends online (Seems to be the only place where girls like me romantically, genuinely), but the connection just isn't there while not actually seeing the other persons face or being able to share physical space with them. I've tried AI but they forget stuff to easily and is not very convincing, plus the above problem. Also I've thought about getting into VR and maybe vr chat or something, but that also sounds like a very different yet still dark path, lmao.

I just want to feel okay again like when I had a couple friends irl. I think we where all getting kinda sick of each other because we couldn't get gfs and felt like losers wasting our teen/early twenties. But we where all probably doing better hanging out all the time then how we are now
