Help Donna's Fight With Cancer

If you don't know me already, my name is Donna Troyer and I live in NJ. I have been divorced for 8 years, and have two beautiful daughters, one who resides in High Bridge, NJ and the other in Olympia, Washington. When I was well, I was an avid gardener and dance instructor, and would travel to spend time with my family. In April of 2012, I was diagnosed with stage IV renal cancer and was given 2 months to live, with over 15 metastasized tumors in my abdomen. Now almost a year and a half later, due to various holistic treatments and a positive attitude, I am still fighting, and have found a treatment that works for me.
For almost 7 months now I have been receiving high doses of Vitamin C intravenously, two times a week, at Doctors offices in New Brunswick and Hampton, NJ. These treatments brought color back to my skin, minimized and or eliminated the daily pain I feel from the tumors, increased and maintained my appetite, and most importantly, made it so I could still basically live a "normal" life.
For the last month however, I've had to drop my treatments down from two, to one each or every other week. I have borrowed as much money as I can from friends and family, and my disability checks just barely cover my basic monthly bills. This decrease in treatment has resulted in a reduced appetite, difficulty in doing simple tasks and a drastic increase in daily pain. I am losing the strength that has kept me going this long, and although embarrassing as it is to ask, I just need help and I am willing to do whatever it takes to maintain my health.
My condition is serious and I honestly don't know what my future holds, but these treatments let me live a relatively good life, and allow me a little more time with those that I love. My eldest daughter has a wedding in the near future and my youngest just graduated with a masters in teaching and has this big world a head of her that I'd like to be a part of. Any amount of help would be much appreciated. Thank-you in advance
