Mother sobs when all her neighbors and Lexi Walker show up to help Secret Santa

Kathy Goff can never seem to catch a break. The 48-year-old single mother has three young adult children who have been diagnosed with dyskeratosis congenita - a rare, progressive bone marrow failure syndrome.

Kathy's daughter has been through two years of chemotherapy and receives plasma transfusions every month. She also has mitochondrial diseases and epilepsy.

Kathy's two sons have bone marrow problems and both recently had pacemakers installed. At one point, one of the boys flatlined but fortunately survived the procedure.

Kathy works two full time jobs to support her family and pay for the endless medical bills. She spends countless hours every week with her children in doctor's offices and hospitals. She is constantly driving to Salt Lake City to take one child or another to one hospital or another for one illness or another.

Kathy's friends say she never asks for help and when help is offered, she can think of nothing to ask for. One friend said last Christmas, Kathy took names off of a giving tree at church - not realizing that her own family was also on the tree.

Secret Santa heard about Kathy and sent his elves over with a special Christmas gift. 15-year-old vocal sensation Lexi Walker joined the EastIdahoNews.com team and sang Kathy's family a Christmas carol and, as the Secret Santa crew arrived, neighbors from everywhere joined in on the special moment.
