Looking for kidney donation

I understand this an awfully strange request on this forum and more than anyone could ask for, but I am going out on a limb in hopes I will be successful in finding what I'm looking for in this time of desperation

A dear friend is looking for someone with blood type O (positive or negative) who is willing to do the utmost honourable thing and donate one of their kidneys. She is a young mother of 3 and is currently on a waiting list for cadavar kidney (nearly an 8 year wait time). Her one functioning kidney is currently at a 17% function and dropping quickly... she will not make it even near the 8 years.

Please, if you or someone you know is O positive or negative and willing to do such an amazing thing, please, please, PLEASE contact me through private message.

Thank you for taking the time to read my plea and thank you in advance to anyone who messages me.

Best wishes for your friend.
