Hope for Caitlyn while fighting Cancer

Hi Everyone, I am writing to you today for my daughter Caitlyn. On April 10 Caitlyn woke up with horrible stomache pain so my husband and I rushed her to Childrens Hospital.. While in the ER they did many tests to figure out what was going on. Caitlyns kidney Dr called while in the ER. (I forgot to mention Caitlyn had kidney failure and a stroke that caused permanent right sided paralysis when she was 4, was on dialysis for 2.5 years, then a kidney Transplant at 6 years old). Well so Caitlyns kidneys Dr calls us and informed us Caitlyn has a form of cancer called PTLD (a form of cancer) which is caused by a combination of certain viruses along with her immunosupression medication. It was a kick in the gut; I couldn't believe what I was hearing. I was giving her the meds the drs told me to give her to keep her transplanted kidney alive. Anyway, Caitlyn needed to start treatment immediately. So we now drive to Dana Farber weekly and get her treatments.This has been very hard on my daughter and our family. She wants more than anything to go on a trip to Disney World and we just can't possibly afford that. We figured it was worth asking for help. Can you help us in any way?
