Gastroparesis surgery

So, some of you may know that my mother has gastroparesis.. it is where the stomach and well (my mothers) small intestines are paralyzed. This causes many problems, including stomach pain, nausea and vomitting and malnutrietion and many trip to Shands Hospital. 
My mom has had it for going on 8 years and let me tell you, it doesn't get any easier. Her life has been put on hold which is very hard for my mom. She was applying to Law school and was always planning major vacations for my brother and I... and now her illness keeps her from doing many things. 
People can say that they understand but you can't fully understand unless you spend the nights with her at the hospital or go to EVERY single doctors apointtment with her...which I have since I was 12 and I am 20 now. 
My mother is probably one of the strongest people I know, she's my best friend and I will do anything for her. I don't care what it takes..
Insurance isn't willing to pay for this procedure and she desperately needs it, I've tried getting a loan or way to pay monthly payments on this procedure but since I'm 20 I have no credit. 

I usually don't ask for any kind of help, it's a Pride thing for me.....but I know I can't have this type of money in a timly fashion...so I'm asking anyone who can help me.. any amount will help... 

I greatly appreciate your time!
