Am I unintentionally starving myself?

in my experience with my eatting disorders, while I was fasting I would often get light headed, dizzy, sometimes I would p out/faint, and also sometimes I would get horrible stomach cramps. so you are probably not getting enough calories, it all depends on your weight, but I'd suggest you try to get atleast 1,200-1,400 calories a day. Its a healthy amount and shouldn't lead to weight gain with as many calories as you're burning.
