I've had hypomanic religiousity (waaaay off normal me. A bizarre trip even within that --ie. 3 very different forms). Also, I feel destined to die by my own hand. But these two things did not come at the same time.
I hadn't been dx'd at the time, and was so confused coming down off the religious thing. Who WAS that???!!! What the hell happened to me?! It was a relief to later learn it wasn't unusual in BP, though I'm still hugely embarassed about it.
Like you, bluebicycle, the Lamictal has shortened episode duration. A lot. Many used to go on for numerous weeks or months. The one above was months. Yikes.
Edited to add: holy crap! I just realized in the midst of that was my most bizarre 3,000 mile on-a-whim move!!!! (Yes, there's been more than 1). How could I have not connected that before???!!!

Wow. Just wow.
