When I am (hypo)manic, I tend to feel jittery and I talk a mile a minute. I am also distractable and buy too much stuff.

When I am depressed, I sleep way too much. In fact, sleep IS my coping mechanism!! I also lack any real motivation to do anything and I don't do a good job of pushing myself to do healthy things.

I can't comment too much on mixed episodes since my last one (that I am aware of) was in summer and fall of 2015. It was what led to my diagnosis. But if I try to remember, I think I was getting like 2-4 hours a night, I felt restless, I was agitated, and I had suicidal thoughts. It was quite bad.
