Urgent Need for Nutrition Drink

I have been sick for 30 years now. The disease is taking a big toll on my weight. I have been on everything you can think of like HGH. Nothing helps. My last dirch effort is Ensure. Found out my Doctor wont write me something for them because my insurance on disability will not cover it. It will cost me $1,000 a month and dont even get a check that big. I am asking for help so I may get it for myself. I can already feel the pains of malnourishment. Please help if you can. Thank You...
