Since you are 17 you have to go through legal stuff like parents permission until you turn 18 which is legal age. You can live a normal life with only one kidney
and not even realize it. I have had 3 kidney transplants two from my parents. You would have to go through lost of blood test
to even see if your a match. If you are a match you hopefully have good insurance cause its very expensive and almost impossible to pay out of pocket. You as the door would probably be in the hospital a day or two and your aunt about a week if all goes well.
