It's like a vicious flu, painful and horrible and seemingly endless, but if you take care of yourself, you will get better. I guarantee it! My father kept telling me that when I was at the lowest of my lows, the end may not appear to be in sight, but it is there. Just hang in there and force yourself to do things you know you should be doing, but don't get down on yourself for not being able to do much. Take it one step at a time. Things WILL get better!
