Man what a bummer reading this thread. At first i thought WOW that's so great for your friend having such a friend like you and now i read he passed away. I'm sorry to hear this man! Stupid question maybe but if i don't ask i will be thinking about it all night. Did you get your kidney replaced back to you? or is the kidney being donated to someone else?
Well that sucks. I would totally freak out if I were you. Now you lost both your friend and your kidney.
I wouldn't be disapointed that you gave your kidney away, I would do the same! if hes a true friend of yours you would do anything for him! Although the sadness of your friend passing away is very, very bad news indeed, but you gave him another chance at life that deserves a medal itself!!!
