MaryAnne, I've been reading this a few times. Its one of those subjects that when you write about it, if you don't understand it, it's hard to get right but
I see you've looked it up and got some information on the disorder and you penned it in a way that works.
You captured it very well for someone that doesnt suffer from it, the constant changes that the mind goes through, the insomnia, the rush of no rest is one that's hard to explain. How it confuses the mind more than people who are not Bipolar.
It's a well written piece. You are amazing at taking something and writing as if you feel everything and I love your descriptions.
