Is 1200 calories enough for me?

Soo im female, 5'1, and weigh 113. If i exercise for an hour a day, is 1200 calories enough for me to consume? i have been trying to get over an eating disorder and I'm trying to lose some of the weight i gained back, and i dont want my body to go into starvation mode again. so do you think 1200 calories are enough, or should i eat more?
