I openly told my boss and my co-workers that I have bp. The environment here is that of a team. We all have each others' backs because our department often gets singled out as making the mistakes even though we are the means of supply to keep the mine running.

My boss now frequently asks me to his office and checks up on me. Just last week he asked if I was getting enough sleep or not (he is also a firefighter/EMT in training).
My other co-workers now understand I'm not just a weirdo or a spazz and look out for me. My day guy always asks if I'm takin my meds and I even told him which meds to give me in the case I have a freak-out or breakdown while at work.

So maybe your boss really truely cares for your health and well being and is just confused and curious as to what is really wrong?

Just another way to look at things. Best wishes and good luck
