So sorry you feel ths way, but thats the nature of the illness. One day it's you're the person, and then the next....shoot me. I don't know your cycle, but it seems to be pretty quick. Have you been diagnosed bipolar by a pdoc? There are many things that can make you feel out of sorts the next day anywhere from what you ate up to an illness. Professional help would be advised to be necessary to get the help needed to fight this or any disease. Hang in there!
