The thing about bp is that it's not really predictable, it's different for everyone every time.

I spent about 8 years in a chronic , worsening depression punctated by rare episodes of hypomania before I finally started to be properly treated for bp. I was totally useless for years.

You may want to talk to your pdoc about your drug regimen. Some meds, like lithium and Depakote are for keeping your moods on an even keel. They can lessen mania, but not so much depression. Seroquel and Lamictal are known to help with bipolar depression. Drugs like Abilify and Geodon are becoming popular for bp tratment. It's usually not a good idea to take antidepressants without a mood stabilizer, they can trigger a manic episode. Also, don't forget exercise and sleep (those are the hard ones for me)!

Above all, keep hanging in there... we're on your side!
