medical bills from my cancer

I found out I had colon cancer about 4years ago. After they removed the first tumor witch was a ten hour surgery they made me go thru very aggressive chemo witch I had to do on 3 different ocations I had to do 30 rounds of radiation along with 7 major surgeries during this time also. I am now on social security disability and that barley pays my rent and bills. I have so many hospital and doctor's bills that r in the tens of thousands of dollars that insurance didnt cover I just can't keep up with. So I am in need of help to stop collections witch has all ready started.  I try to help others when they need it and rite now I need some help.  Anything would help me out rite now so I'm asking for my friends to help me out of a very hard spot so if u could help me out I would really appreciate it and thank u very much and God bless u
