Now this is a strange question but I think I'm on to something with what causes my depression. I have not been diagnosed with bipolar but I have been told I have had post natal depression since my son was born over three years ago.

I find that my mood goes from one extreme to the other and it all seems to be tied into my hormones. Usually around the last day or two of my period I find my mood elevates and I start to feel more confident and energetic. This increases day by day until around day nine of my cycle I am on a high - I am bursting with energy, lose my appetite, I am sexually charged, I get hooked on a certain idea and I can't shake it - it could be a film or a job idea but whatever it is I just become fixated on it and become quite hyper with my plans about what I'm going to do. I also take more risks because at this time I feel like I am invincible. Then, after a few days of this wonderful high, it suddenly goes. I gradually get more and more depressed then, am lethargic, binge eat and can barely get myself out of bed.

Every month this mad little dance is played out and I'm at a loss. Do I sound bipolar? Am I perhaps just over sensitive to my hormones? What the hell can I do?

I would really appreciate any ideas!

Many thanks.
