Medical Fund for Irene Mercer

Most of you know my mother, Irene (Mercer) Moore, as you know, she has always been there for anyone in need, a wonderful sweet godly lady, always ready to pray, talk or listen to anyone in need, always with a smile and a kind word. 
Well now, she needs our help. She had a cancer tumer removed from her left inner jaw and her jaw reconstructed with bone and tissue from her left forearm. 
Medicare didn't pay for the entire procedure, so she needs assistance with those bills and my sister.
Donna Jones, whom my mother lives with has used all of her vacation days, is having to take off work to take our mother to Little Rock for her doctor appointments without pay.
Neither of them like asking for assistance, but I am asking for peoples help for our mother's medical expenses. Any and all help will be appreciated.
