I think it's more acceptable than it used to be. Education, people speaking out, but I have to admit I am hesitant to be entirely open about it, only those who need to know. I have told my older children because they run the risk, but did not tell my family doc. My psych doc most definitely. My family knows, my husband knows, but I feel it's a private issue.
Why the fear? I don't want people to treat me differently or even be discriminated against. I can function quite normally with a minimum of the right combo of meds and have recognized triggers, thus treating and preventing severe highs and lows. Not that is picture perfect all the time, but manageable.
I am honest on here, and an outside support group that specializes in depression and bipolar. I have bipolar disorder but I am not bipolar disorder. So much more than that
