Darryl's cancer medicine

I was diagnosed with multiple myeloma a month ago.  My doctor said after three rounds of chemo, I would be okay. Well I completed round one this week (8-28-17). now it's time for round two with a different drug (revlimid). I called to order delivery and was told I need to send in $6000 co-pay before they can ship it. I was floored. I'm not one to beg or ask for help unless it's absolutely necessary. I am praying for anyone's help. The doctor's staff is trying everything they can. Any help would be greatly appreciated. any overage can go to the Leukemia-Lymphoma Society. THANK YOU!!!
