chemo Co pay

I first had cancer in 2003 I had  cervical  cancer and had surgery and radiation  i have been in remission until this past march  i was at work and was in a lot of pain and went to the hospital and found out i had a bowl obstruction and had to have surgery .  During surgery they found out that i have cancer in my small bowel they took what they could but iy had went through the wall so now I have to have chemotherapy cause I have stage 3 colon cancer. I just found out the Co pay is 900.00 I have not worked in a month and half do to the surgery  I have insurance  with my job but my Co pay is so high I don't have it. I am only getting 60 % of my pay and have to live off of that. So if you have it in your heart to help me  I would be so appreciate .
I need this to live this is my only option. Please help me. I have prayed on this matter. I am at my wits end. I am not ready to give up. Thank you
