Went through a similar thing, two years on I’m still not recovered.

Just to say that even though it might not feel like it right now, it eventually gets better. You have to give it time. Sometimes a long time. And seek support from friends and family but also from a professional.

And once you’ve recovered, learn the signs so you can see it coming and prevent it. Leaving a shitty job or even a profession that doesn’t work for you anymore is always preferable than getting burnt out.

Good luck, friend!
