Help Lisa Overcome GI Fistula Surgery Costs

I'm Lisa 52 years old. A massive stroke & brain surgery survivor. I have been dealing with a GI fistula for about a year. It's making me incredibly sick. I have an appt on July 9 with a cholorectal surgeon to strategize about surgery. I've been told that it's an expensive surgery that will cost between 8k-10k out of pocket.
