How can i get a normal energy level?

My entire life I feel like I am missing out on it because of my chronic fatigue, I walk up a flight of stairs and I am ready to p out. So bloodwork says that I have a low blood count, might have sickle cell trait (runs in the family) and I have iron deficiency anemia. I want to run and live and be attentive, but I am just so tired all the time. Please help me. I hate to exercize because I have no energy for it so that just adds to my fatigue. I also have high cholesterol and I am very slim.
