I can understand. In a lot of ways I miss it as well. Feeling like you're on top of the world, able to do anything you want. I had self confidence, was able to do things that's almost imposable when depressed. Whenever I get manic I feel very high, very happy, end up studying all day long without rest. But I always found that I tend to do stupid things because I was so "high". Like say things I didn't mean, or act kind of weird. The crash afterwards is pretty bad as well...

I also don't miss the lack of sleep when in mania... I'd honestly walk back and forth for 4 hours into the night just thinking and analyzing because my mind was just so active. Made it almost impossible to sleep.

I miss feeling so great and amazing (Doesn't help that I hardly ever feel completely happy so it makes me miss it even more). But I don't miss the negatives. It's most likely for the best.
