Why couldn't you work part time in school?
Perhaps following the "weekends only" paradigm outlined in the post below. In many job markets hospitals are so short of critical care nurses that they are willing to pay full time benefits for part time work! In addition, due to your condition CRNA programs SHOULD try to accommodate your schedule at least to a degree. You MIGHT even qualify for mandatory reasonable accommodations under the Americans with Disabilities Act (see an attorney who specializes in disability law). Of course you wouldn't want to point out your situation until after acceptence if you were going to go this route.
In addition, have you investigated lower cost alternatives for treating your condition? Many people purchase their medicines in Mexico or Canada to save large amounts of money. Some people have success with "natural alternatives" instead of main stream treatment. Herbal therapies and even more esoteric treatments such as homeopathy seem to offer benefit to some people (even IF its placebo it might still be effective heck in some studies even mainsteam meds like Prozac struggle against placebo). Extreme dietary modifications such as Pritikan or Ornish, might prove benefical for some conditions (the benefit of caloric restriction ALONE has proven to have great merits against a wide variety of aging related ailments at least in labratory animals).
