I live in a different state, and is much more friendly with benefits, but I applied and got on medicaid even though the online calculator said I don't. It doesn't hurt to apply, the worse they can do is turn you down as long as you answer everything truthfully.
As for food benefits I never came close to getting it. From what I understand, without dependent children it is very hard to qualify, regardless of state. I had to donate plasma twice a week to eat for quite a few years.
I am sorry that you suffer and struggle so much.
