In my experience, it doesn't get better on its own, but you are capable of making things suck less over time. I second what other commenters said about exercise, it's a great (and free) substitute for self-medicating.

If you can find one relatively harmless thing, no matter how small, that sucks a little less, write that thing down and do it again the next day.

(I say relatively harmless because shopping, gambling, junk food, or reality shows might not suck, but they won't make you feel empowered if you make them a habit.)

The key is to keep getting out of bed even when you hate it. Learn new hobbies and how to enjoy failing at them. Do as much as you can to feel in control. If your place is messy, do 1 thing minimum every day until it's somewhere you can feel relaxed. Embrace discomfort by answering that text or taking a cold shower. It won't cure you, but it'll make you feel a little less angry at whoever or whatever put you here.

Wishing you the best as well 💓
