WINCHESTER, Mass. (AP) — A Massachusetts mother has a new outlook on life after receiving a kidney donation from a complete stranger.

WBZ-TV reports Nicole Baltzer never thought about being a living donor. Then she read a Facebook post about a single mother with lupus who needed a new kidney.

Baltzer says she remembers reading about Kara Yimoyines and thinking "this is so unfair." She decided to see if she was a match for the fellow Winchester mother.

Several months of screening later, doctors announced they had found a perfect match.

Yimoyines says the donation has helped her be involved in her children's lives in a way she hadn't been before.

The two women are now friends after finding they shared more than their kidneys in common.
