I understand your position, and hope that your supervisor is indeed genuine.

I had struggled with owning up to my bipolar. I decided to tell my supervisor of the situation. I explained that my issues were due to both work and home stresses, and that I was slipping into a deep depression.

I had been bought in to his office due to absences. There was also concern from my coworkers that I seemed to be not myself, and that they were concerned. He then mentioned that he to had noticed.

I was encouraged to get help, and do what I needed to do. The support that I have been given is priceless.

You can give as much or as little information as you feel comfortable. I wish you well, and hope that you the support that I have gotten.
