With my first pnurse it took him talking to my dad (I was 17 I think). My dad simply said "she gets hyper, then she gets really sad" and the man just said "sounds like bipolar to me." That's the story of my first diagnosis.

I'm now diagnosed with schizoaffective disorder after numerous hospitalizations for psychosis with no mood symptoms and a thorough intake that asked more questions that never came up before.
