Have you tried applying for Medicaid? You can apply at your local Income support office, you can apply for food stamps and what not there as well. My kids have the Medicaid and all of their expenses even prescriptions are covered. I personally was very lucky i got the state coverage insurance before they had a wait list, my husband has been on the wait list for over a year. Those are all the places that i know of.

Here is a website to Income Support NMHSD - Income Support Division
you should be able to download the applications and mail them in also, thats what i do.
