I understand exactly what you are dealing with. I too am bipolar II and instread of getting "manic" i get irratable, and just ticked off over the littlest things. I know that I am being irrational and just plain old mean but I cant contol myself and I too have to go be alone so I dont make anyone else feel like they have to walk on eggshells around me.
The hardest part for me is I have 3 young kids and I am probally screwing them up by being this way. I hate myself so much and some days I feel like they'd be better off not living w/ me. Who wants a total b**** for a mommy?
