That's what I wish I would have done. I kept a daily log of my activities for the first three months, and submitted it to upper management after I submitted my resignation. It proves that my managers were lying to them.

I started taking Muay Thai kick boxing lessons after I quit, since I felt kicked around and helpless for most of the 6 months I worked there. It's helping, but I'm still having nightmares and intrusive thoughts about management.
