I'm only going to use my last manic experience for a comparison.

I was functional the entire time (as in, going to work, etc.). I don't think I was acting bizarre around others. Only person who could tell I was acting weird was my husband. I work alone and don't talk to very many people. I had like three moments where I felt euphoric, but mostly it was just a terrible, awful, anxiety ridden experience. I had two days of elation, and then just sky rocketed up into a bad, frantic psychosis.

I wasn't irritable during it. I wasn't paranoid. I thought I was dreaming. There were some scary hallucinations that were probably due to some slight paranoia.

My husband told me that I SEEMED euphoric and wouldn't believe me when I insisted that I just felt bad.

In all honesty, I don't remember the entire experience very well. I'd have to be reliving it to fully remember what it was like. It was just bad.

I'm sure your manias have been worse.
