Best / Cheapest Health Insurance For Single Divorced Mom?

I live in the Indiana. Does anyone know if I can get help from the state with my health insurance? I’ve got two kids who are covered by their dad, and my job is considered part time, although I work 44 hours a week (go figure, I work for the gov’t. ) so I’m not eligible for insurance through them.
Any health insurance advice would be helpful . . . the cheaper the better right now. I’m on a tight budget.
