I have a lot of the same feelings and I think some of it may be the season, and a lot of it is not getting enough sleep. I'm still taking stuff to help me sleep, and it's better than it would be without, but I'm just not sleeping. Then I'm tired and cranky and useless, then I worry more so I don't sleep, and bah.

My way of dealing with this is to give myself permission to feel bad for a while, and let things go, and then pick a date when I'm going to make myself stop. And I do. I also find some little thing to perk me up, whether it's a good smelly lotion or some chocolate or tea. Or a movie. Something small that makes me feel better. Because it is no fun feeling like that, is it?
