I can understand going through some Sugar Honey Iced Tea to get to an end goal, but if you don't know what the end goal is any more, and you aren't enjoying where you are, then it is deffo time for some soul searching, which it sounds like this is where you are at.
No job is ever worth your health - physical or mental.
Stay safe, and look after you.
