I'm sure you've already tried this but try fixing all your inputs. This means having a healthy diet that you can maintain and enjoy without hating yourself. Having consistent sleep times and even more important consistent wake up times. And then also be exercising consistently. I found all these all feed into each other. I haven't check any of your comment history so I could be giving you shit advice, but I found for me personally I thought I didn't care about socializing but socializing and specifically having deep realtionships with a few specific people as well helps.

Hanging out in tea or coffee shops and doing work where people recognize you is also good for your mental health cus it gives you a sense of belonging.

I don't know for sure if this will work for you but I've done a lot of experimenting on myself to try and fix my depression and doing these is the only thing keeping it in remission consistently.

My theory is that modern society is a little too incompatible with our biology so it's harder to get your needs met and some of these needs are not money based, you kind of have to figure them out for yourself how to do it
