How can I make this possible?

I am a 26-year-old female who is very seriously considering going the "Vegan route" in the near future. Here's the problem: I am a peritoneal dialysis patient. (For those of you who are not familiar with the medical term/disease, I suffer from kidney failure and have to use a glucose-based solution to filter toxins from my body.) As a P.D. patient, my diet MUST consist of high protein, low phosphorus, and potium rich foods. Could anyone suggest some possible menu items I could eat that with satisfy my dietary requirements? Any response you could provide will be greatly appreciated. Thank you.
