Will i be eligible for goverment aid or some kind of help somewhere?

I am a single mother that works in the state of ohio as a lpn and i would like to go back to school to get my rn license. is there anyone who knows if i would get help paying for school? i have one child and make about $2000 a month...not enough!! If so does anyone know where i can research info or share any words of wisdom? Any info would help- thank you
