I'm bipolar and have ADD, and could see them possibly being related, but repressed emotion? That's just about the funniest thing ever! One of the difficult things about being bipolar is that I can't repress these overwhelming emotions if I tried!

Think of it this way.... are you comfortable with your emotions? Probably not... we cannot express them in normal way.

I used to be hyperserious as child. Things happened... i started having manias... and yes, it feels like my brain went "so you will not be spontegeous? Well, I am gonna be spontageous for you!".

For me it helps to allow myself these emotions. Allow myself be crazy (within limits).

You say people respond to meds "well". I don't know... from what I seen it is almost always hella ride and episodes are still bound to happen. Maybe the more we insist on normality the our minds seem to backfire. If it was biochemical, shouldn't the chemistry be enough? It never is though.
