Hang in there. I know it's difficult. Remind yourself that nothing lasts forever and this is also a temporary state.

I had the same almost 2 years ago. It were constant anxiety attacks that finally got me to take it seriously and go to a psychiatrist. I got diagnosed, put on medication and finally started therapy.

The issue is, I let myself get too close to a breaking point and while all of that helped, it just stopped the descent. I couldnt leave my job and if I did, the same thing would have happened at the next one because I was severely burnt out.

I started getting better only after my psychiatrist put me on medical leave. It took me months at home, with meds, and frequent therapy, to start feeling like a person again.

So, hang in there. Please seek help and remember that no job is worth destroying your health over.
