If you could make things worse, then you haven't hit the point where you have nothing left to lose. And if you still have something left to lose, then you're relatively blessed. Mental illness notwithstanding, anybody who is reading this has a pretty decent lot on life given that they have access to internet and a device to browse here, plus some amount of leisure time. Those data points alone put you in a better living situation than probably more than half of the world population.

I can't speak to your exact situation, but I'm optimistic that you'll find yourself in a happier place within a few years. You seem like a thoughtful and caring person, and you're right that that's not all it takes, but it's enough to get started with. When I get anxious, I envision a simple flowchart:
Can I do something about this situation to improve it?
If no, then don't worry about it and just ride it out the best you can. Worrying is wasted time and energy here.
If yes, then do that thing. Try. If you failed to improve it, at least you tried. And you'll wake up tomorrow and try some more. But don't delay the trying by spending time and energy on worrying. Worrying is wasted time and energy here.

Both result in the conclusion that worrying is an illogical step that you should just go ahead and skip. And that's how you can ease your way into a "fuck it" attitude!

My other lifehack mentality is to figure out how much more time and effort it would take to get an A+ result versus a B result. If it's a significant difference for a pretty minor improvement, I say fuck it and move on. Beef Wellington is really good, and I'm glad I've taken the time to make it a few times in my life, but burgers are really good too and much much easier to make.

I hope this was helpful to you in some way. Rock on, my dude!
