My husband and I both had to deal with situations with horrible supervisors at points in our careers. I guess I just want to communicate that while you can't help but feel angry, try to channel that anger towards doing the things you need to do to become more independent and less vulnerable. And its not just science, or academia. There are A-holes everywhere. What's important is becoming less vulnerable to petty power. To do that, you need to have such a strong CV that you can call the shots. Then you can walk into whatever job you want, whether its in academia, industry, gov, etc.

Good luck. Sorry if I am seem harsh, I understand you need a place to vent, but I also know that to be strong you need to feel strong, so that is why I have been trying to stop the pity party and encourage you to channel the anger towards something more productive.
