I may be bipolar II or NOS (Not Otherwise Specified). My hypomanias were so subtle I didn't know they were there. Then when I took Risperdal it "unmasked" the cycles. I became definitely hypomanic for 2 days, depressed for 5, back and forth. Previous to this I had periods where I was more productive but most of the time depressed and anxious.
When I first started taking Paxil a long time ago I felt really good for 2-3 days, never to return.

It may have been hypomania, but to me it just felt normal. That was the only time in my whole adult life I felt normal. That still seems cruel to me, to have a taste of being normal.
Anxiety is a big problem and now and then a panic attack or days of anxiety will come to a crescendo with no rhyme or reason. I believe this may be a form of hypomania.
Right now I'm on a low dose of Zyprexa and am stable at a very depressed and anxious level. It's not the drug for me and my app't with a new doc on the 27th seems like an eternity. (I'm on a cancellation list.) We'll see what she says about diagnosis.
I'm very sure my diagnosis is Bipolar of some sort. I think my previous doc says "maybe" because he didn't believe half of what I said. I'm not making this stuff up.
Sorry for the long post. Just felt like typing.
