Yes, I've been diagnosed mixed state. I think I have agitated depression which is mixed mania (a form of manic-depression) since 14 and I've seen it in many relatives on my mother's side. I have had incredible racing thoughts over the last 35 years. I can be depressed and agitated and/or excited and/or racing at the same time. I have long history of treatment and tons of ADs (only one which I've had positive response to was paxil for several years), anti-psychotics, benzos, full series of ECT. Presently started ritalin which has eased my agitation which is my biggest problem. Been on lamictal since 2003 and has not done a thing (same with lithium). ADs can cause agitation and/or mania in some BP patients so be careful.
