I have felt tis way before, and still do sometimes. I am unsure how to change it tho, as it still comes and goes with me. One day i am deeply depressed, and the next day i am my old self. My problem now, is the constant onset of Headaches. I dont want to do anything, I want to sleep all day, and am mostly miserable. I feel for you hun, as I am in the same boat most days.
