I put my hair in rollers

I want big hair right? and my hair is like to my ribs so naturally, i only thought it was get some waves... SO THAT DIDNT HAPPEN, i have afro now.. i dont.. understand this never happened before is spent three hours just trying to get it to calm down. it didnt work out so i just put it in a ponytail and wait for it to hopefully calm down. it's really overstimulating :(
