Waves of Sickness!!

After being sick for two years straight, I have discovered that my sickness comes in waves. Sometimes I don't feel bad at all, like this summer f. eks. I were so optimistic then, hoping that it would soon be over and I could go to school every day!
So know I in a down wave, it has lasted for a week. My body hurts so much so I sleep all day, but then I can't sleep at night. This is the third night that I'm up. I'm starting to get quite depressed!
