I always feel annoyed/irritated from hunger. But I also pound caffeinated coffee constantly, too. Which causes irritability, omg. U can still drop the weight u want to without exercise. I'm sorry about your health stuff/pain. One of my arms got sprained badly last year. I couldn't even put a jacket on without screaming in pain. I know that crap hurts alot. Ive heard antidepressants can cause weight gain. So what did u make yourself to eat? I ate some leftovers I had cooked yesterday. Yeah, I notice I get a blast of energy from food to exercise again.
