How can I build up my immune system after breast cancer treatments? - shingles of the breast

I have a very weak immune system, because I chemotherapy, radiotherapy and other cancer treatments and breast surgery. Since I finished chemotherapy and radiation is less than one years, I had to fight herpes, meningitis and had 2-infection in my left breast and radiation has to go into surgery to remove the implant and replace it. I am sick and tired of being sick and tired. What can I do? In addition, 40 pounds generated, and the hatred of weight gain.
