Changing meds... losing my mind

The lithium has stopped working... Pdoc put me on Deprakote...going from 0 to 1500 mg FUN!!!  Rapid cycling and mixed cycles are all I know these days. I am losing my mind... I feel just as bad if not worse then what I did before I was diagnosed.  Husband is not being supportive (like he ever was).. This weekend he told me that he knows that I have bipolar (i have been dx'd for 2 years) he would just rather not hear about it.  Wonderful, huh? I am at my wits end. Last night my suicidal idealition were so bad... I am glad that I had someone to talk to because if not I don't know what I would have done. I am tired for staying up all night so I was completely no help at work (which does not make my bosses attitude toward me any better) which spirals my thoughts out of control. Someone please stop this insanity...
