manic cycles getting closer together

This is my first post on this site. I have been fighting bi polar depression for over five years. I am a 45 year old male, married and have three kids. I have been on several meds with little or no help. Currently I am on Depakote a drug used for epileptics. Currently the dose is 2000mg a day 500 mg over my normal. I am having problems controlling emotions right now I go from angry to crying in a span of less then an hour followed by laughter then a feeling of invincibility. I go from everything bothering me to not a care in the world. In the beginning of my diagnosis things were somewhat easy to manage the cycle of emotions and moods were not as drastic as they are now. I feel like I am losing control of everything right now. I find myself lying to my wife over stupid stuff, I can't seem to concentrate and stay focus on anything. At times I just want to hide until this all passes. I am currently between doctors due to my insurance and my provider not being able to come to terms with each other. So I lost my psychiatrist and my therapist and starting with new one now. Also the pastor of my church that I have gone to a few times has recently left our church for a new one. I have never had these sped up emotions before and I am having a hard time with it. Has anyone else had this happen to them?
