Wow, you have a lot to deal with. This kind of situation is something I deal with a lot with my clients here in the UK. There is no space here to go into huge detail (and in fact, I've written an entire book on it - see my profile) but here are some thoughts:

1. Use goal congruency to show your boss how you can both have what you want. Work out what thy want, and show them how treating you properly will motivate and enable you to give them exactly what they want for themselves. If you feel it's right, show them the converse is also true.

2. Try to develop a relationship with them - perhaps based on your new-found mutual goals.

3. Collect evidence - preferably written - to lock real-world events into focus. There are various ways to do this without it looking contrived.

4. Build alliances around your boss so that you develop a platform of credibility and respect with the rest of your organisation.

There's so much else I could say - about managing stress, diffusing irrational behaviours, staying strong to fight this battle daily, etc. but I hope that may be of some help to you for now.

Good Luck!
