Hi there. I can relate to your dilemma a lot. Work is a big part of life and it can have very bad effect on your health if you are in a bad situation there. In fact I've just given notice at my work. We had bullying free loading and constant intrigues going on at my department for years. People responsible for the situation manage to deflect all blame and me and my supervisor have been constantly attacked and made miserable. We are both leaving that place. It was not an irrational move. My health is fine now but it would suffer if I staid. I know not everyone can afford to leave work, but I think you should protect your health first. If you go into episode you will lose the job anyways and will have to take expensive drugs to get back to normal. I'd say switch to a department where you are the most comfortable and try to limit your expenses. Look for something else in a mean time that has better environment and pays more.
