At first when I was diagnosed I had to research it and still questioned it. After some time on treatment I asked my pdoc if she was sure I was BP cause I didn't have all the symptoms. For a long time my mania was severe irritation especially when I was prescribed an anti-depressant. She replied, " Would the meds work if you were not?" So that is kinda what sunk it in for me. I have had many med changes since then but I also had a wild manic attack after that too which really paved the way. I guess the another reason I did not want to accept the diagnosis is because the stigma that goes with it.
