I'm in a pretty similar situation as you, my dude.
I collapsed in on myself after I graduated. I never really gave any thought about what I'd do after college. I didn't know who I was or where I was going in any capacity. I was lucky enough to get a job through an acquaintance. The money is good, but its pretty soul draining too.
I started drawing and painting to cope with it, and it helped keep my mind off it for a little while. Trying to learn a bunch of skills ended up just being distraction from the real issues, though.
I started seeing a therapist last year and its probably helped me the most so far. They've helped me start tackling the bigger issues that I had been distracting myself from. Isolation is a big one - finding a group through MeetUp or something similar is how I'm planning on tackling it.
Don't give up yet my dude. Give yourself some room to figure yourself out and you'll figure it out. If you have access to a therapist it might help.
Hope things get better for you bruv
