I mimic DeeplyHurt77 in that my self esteem coincides with my depression. When I am having a particularly bad bout, my self worth is pretty low. I'll go through extreme guilt, pity, etc.

Though, when I am so so or having a good day, my sense of self/image is pretty good to even strong. But it can be, much like Deeply said, a whirlwind of emotion and such.

The oddest thing, when I am depressed, and my self worth is low, I am usually nicer, more selfless...and when I am feeling good and my confidence is high, I can be a jerk...I wish I had a way to "fix" that...
