I have 30,000 in medical bills due and I am a single mom

I am a mother of a 4 year old. My husband kicked me out when I was sick 2 years ago, and told me he did not want a sick wifeAlso, he told me he married me for a green card and he never loved me. I moved back home from Dallas to Colorado to live with my parents. He is a Doctor and has not gave me child support for almost 3 years. I get food aid from the government but they have not served him for child support. I have severe scoliosis with Harrington Rods in my back and have had alot of pain in the last 3 years, with so many medical tests on my back and needing another surdery in June, and raising my son on my own I have $30,000 in medical bills. Please help me.
