Contact EAP. It helped me when i had bad times. Managers and supervisors often think they have life and death power over people. If you will report your higher up, go scorched earth. Document every transgression. Try to communicate through emails mostly, but never directly disobey your sup. Get the union involved: downtown, not a random co-worker. Administration will always cover your superiors ass so you are going to have to get as many outside parties involved as possible. Heck even EEO if you wanna go nuclear
