I was initially dxed with Bipolar disorder when I had a stress breakdown. The minute the doctor said Bipolar, my response was, "I'm not Bipolar." For 8 months through toxic medications, short term disability, embarrassment and humilation, sometimes when I couldn't see from being overmedicated, all I could say before I passed out was, "I'm not Bipolar."
When I was finally hospitalized and the new doctor's started taking me off of the combination of drugs that had cost me all of my executive functioning, one of them said, "Has anyone ever talked to you about Post Traumatic Stress?" and everything clicked into place for me. The bloody nightmares from which I would wake up screaming, the certainty out of nowhere that someone I loved was dead, the anxiety and panic attacks... it all made sense. I was relieved beyond words.
When I got out I couldn't wait to face everyone who had insisted that I should just admit I was Bipolar and finally add on to mny earlier statement, "I'm not Bipolar; I have PTSD!" I guess it's all a matter of the framework it's presented to us in. For me, "I have PTSD," was a welcome change from where I had been.
