Help Tina Ray fight cancer

I am hoping to get as much help possible for my sister ( Tina Ray) who was recently diagnosed with cancer ( Melanoma ) after being sick for eight months and being falsely diagnosed by several doctors and hospitals. Tina started her treatment last week which is immunotherapy, in Newnan Ga. This treatment will run for 9 months and then they will start radiation therapy so she has a long, tough road to take. This is especially hard for Tina seeing that she just lost her husband of almost 40 years just months ago. Tina has worked driving a school bus for the last 13+ years and paid out plenty in insurance policies which are now saying they do not cover her type of treatment. She has been placed on short term disability through her employer which will soon lead to long term. So her monthly pay checks will only cover her insurance policies at work. Anyone that knows Tina knows she doesn't like to ask for help and would give anyone the shirt off her back. I pray that if anybody can donate anything (prayers too please) it would help so much and would be greatly appreciated. Thank You
