Sorry you're having such a bad time. I agree with the others who said you really need to see a pdoc to get a diagnosis, and that your boss is not qualified at all to do so.

I noticed one thing I wanted to mention: you said you took a week off to deal with a normal depression, "nothing big, just normal life crap." Feeling so bad that you need a week off is not normal at all. I'm not trying to make you feel worse. Just wanted you to realize that is not normal.

I hope you'll talk to a doctor soon and tell them everything you told us.

Hang in there.
