It doesn't matter how long you have been fighting as long as you keep fighting. Sometimes the cycles take longer than others. I don't know how long you have been feeling this way, but I remember a couple of months ago, I was talking to my pdoc about how I felt like nothing was helping me pull out of a pit of darkness that I was in. He talked to me about it how my mood would shift eventually. He told me to trust him on that. He was right. (It took an antidepressant to help, but he was right). I have that to hold on to now. Think back, have there been other times that you have felt like this? How long did it last? Did you eventually feel better -- even if it was two months later?
