The fact that my cycles have no trigger, for example I can wake up suicidal and stay that way for days, is what made it so easy for pdocs to dx me with BP.
And yes I have to agree that while BPD consists of reactive moods, like in the case of neurotypical people, the emotional reaction is far from typical, it's bloody extreme. Which is what makes having this damn disorder so horrid, you KNOW you're over reacting, but until you aquire the necessary skill set, all you can do is hate yourself for behaving like a dangerous 2 year old.
I'm always baffled by people posting about how something triggered the depression or mania... I mean I get the stress factor, I think we can all agree a BP person is allergic to stress, but specific triggers?
Ps. If I won the lottery while severely depressed I wouldn't give a damn. I would have to wait for the depression to lift before I even realize I have a shitload of money.
