Hi quas

I don't think its unusual too much to doubt diagnosis if we are not in an episode and reflecting back on one and wondering if there may have been other factors that contributed to the mood state other than BP.

Your anxiety may likely have contributed to your last Manic episode that required hospitalisation.

I guess when I do this personally its a way of me questioning did I really do that because of xyz - I'm trying to rationalise everything in my mind.

Chance are if you did have a genuine "Manic" episode that required hospitalisation; yes, you are Bipolar. You're just trying to figure out what went on at the time.

This is just my personal opinion on this.
