The problem with the "what makes you happy" question, while a totally reasonable thing to ask, is that sometimes when you're in the hole, you don't even know what makes you happy. Or what typically makes you happy doesn't anymore.

Admitting you feel that way and asking about it is good first step and people here have really given a buffet of suggestions. Talking to a pro and physical activity will be a good start. Psychedelics (particularly mushrooms for me) really can help, but you need to be prepared for what you see, it's not always a good time if you're using them to do work. But on the other end you really do gain that perspective. I wouldn't "recommend" them, but I also wouldn't discourage them, it's pretty personal.

I hope it works out for you, there's lots of things to do out there, and hopefully you can get to more of them.
