Should I tell my boss I am bipolar?

I was diagnosed in March. I’ve been through so much the last few years it has been horrendous. It kind of came to a crescendo in my being hospitalized (from being a very capable successful person) to a complete wreck. I was diagnosed as Bipolar II.

After leaving hospital I was really battling for seven months. Plus I had no real job. I have to earn to live as I live alone. I also had taken care of my two parents for ten years.

I was phoned late last year and offered a job, from a person who knew me in my industry. It is a very high pressured job and very demanding. I feel this is causing my moods to be all over the place and at work I feel, I am perceived as moody and volatile. To some extend they accept it, but I feel they are confused a lot of the time. I really and truly have no control over this, and I have been trying to get to see my psychiatrist since December 1st, but he is fully booked.

I really need help first of all to make a decision, should I tell my boss I am bipolar? Would this assist them in understanding? Or would it work against me. I wish I could change professions (stress) but I feel I cant, it’s a tough market out there, and I have only experience in this field. I am quite desperate to get help particularly as my psychiatrist seems so unavailable. Sorry this is so long, but felt it needed correct input. I also feel really unwell most of the time.
