I've had depression make me sleep too much but then have insomnia, several days of each at a time. Severe depression makes me hurt everywhere, like my limbs weigh 500 pounds each, and exercising doesn't help lift that feeling at all no matter how many doctors, friends, or well-meaning people tell me it will. It just makes me hurt more and feel more exhausted. Perhaps it changes peoples' chemical imbalances sometimes but it sure hasn't changed mine. I get hungry, sort of, but nothing sounds good so I end up just having bowls of cereal or cups of tea. I try to eat fruit every day and take multivitamins to get some nutrients into me, but I don't always care enough to make the effort. (Because peeling a banana is about as much effort as I'll put forth. Everything else seems like so. much. work.) I was on Zoloft then switched to Wellbutrin which didn't work at all, but now on Celexa which is somewhat better. At least I'm getting up and doing a few things around the house on most days, but it's hard when my body feels like it can't resist gravity no matter how much I want it to. Anyway, you're not alone feeling the way you do. I hope you find a med that helps, and can eat some foods that help you feel stronger. Good luck to you.
