Why is it that depression is acceptable and then add mania or hypo mania and people freak out??

I haven't told anyone except a close co-worker who also has mental health issues, and we vent to one another. Even she (whom I have had to take to the ER for a mental breakdown) acted a bit different when I told her. She is very supportive but when I wanted to talk about it some more she changed the subject. Just that semi-neutral reaction is why I will keep it to myself as long as I can.

I have done alot of thinking and my feeling is as long as I am on medication and am getting treatment why do I have to live under a label. I will try not to dwell on my diagnosis but concentrate on my treatment. Obviously I'm having a good day today.lol
