Esketamine did a lot to help with the overwhelming anhedonia. For around a year I was more able to enjoy doing things. Not perfect of course, but it definitely helped. ECT helped too, but it didn't last as long so I don't recommend it as a first plan. TMS helps some people, just not me.

Meds can help take the edge off too, but they aren't going to fix it. And in this hellscape of a world, I don't think there's any complete cure likely.

It might be worth looking into pursuing a hobby you care about more seriously, if you have one you do or are interested in trying. Having something regular to work on you can enjoy even sometimes gives you something to look forward to and feel kinda good about. For me that's mostly music, but it could be writing, board games, fencing, whatever.

You're worth keeping alive. I hope you can find something that helps.
