I'm new

What should I expect during the first year after chemo treatment? After treatment, I felt tired and sick and my memory was limited. After six months, I thought I would be back to normal, but I am still felling tired, my body aches, and my memory is really bad. I went back to school and I feel like i am going to have to drop my classes because I cant remember things. How did I get rid of these feelings of tiredness and memory loss and body aches.

I would appreciate all your help and advise.
