I am new to the site (just joined today) but I can try to describe what a mixed state is like for me. I think I spend most of my time in a mixed state. I actually didn't know there was a name for it until very recently. But for me, it's like outside I'm manic. You know, talking too fast and too much, not sleeping, trying to do everything. But inside I'm so depressed I can't care about anything. My outside actions won't match my inside feelings and I don't know why. I've heard that mood stabilizers help but I'm still searching for the right one. Hope this helps. Sorry, I'm not very good with words.
