Hey, I can totally relate to your experience (though mine was a little different of course).
I'd been diagnosed as bp2 for years. About five years to be exact. My hypos were never any trouble. Just a lot of creativity and me being silly. I never spent tons of money. I didn't do anything reckless. I just felt really good and did a lot of writing.
Then, I don't know what happened, but I had my first full blown manic episode at the end of january. It was awful. I believed I was enlightened, that I could save the entire world with my positive energy, that I was dreaming, and in order to release all of this positive energy I had to "wake up", and the only way to wake up was to take a bunch of pills for some reason. It was really intense, and I ended up inpatient after a pathetic attempt at an OD.
It was really traumatizing. I'm still recovering. Luckily for me I wanted to keep my enlightenment a "secret", so the only person I told about it was my husband (and the inpatient doctor when I was IP). I also had hallucinations, though non audio. I was just psychotic and out of my mind manic. I read some of my journal entries from that time, and damn, I was so out of my mind.
Anyway, just wanted to let you know that I relate.
Just, horrible experience.
Never want to experience that again. It was NOT pleasant.
I hope neither of us experience anything like that again! (Though yours sounds like it was an euphoric experience, and mine was just terrible.)
