Oh, I replied on your other thread and just saw this.

Your situation reminds me so much of mine. The abusive boss, false accusations, and damage to your mental health caused by obsessing over the situation.

You do need to get out.

I'm wondering though if you would be better off asking to be laid off? I had been planning to just quit in March, but right before my Christmas vacation, I got hauled into the office, accused of something I didn't do, and told to sign a paper that indicated I would be fired the next time I made a mistake. I decided to demand severance and got laid off. I had enough extra cash to spend two months in Europe and unemployment waiting when I got home and started looking for work again.

If you are interested in that route, I might be able to find the letter I wrote demanding severance. A friend of mine who is very good at negotiating exit packages wrote it for me. It might be a long shot at a non-profit, but... it doesn't hurt to ask, right?

Good luck -- I hope it went well if you did give your notice today.
