HELP I'M OUT OF CONTROL!?!? D:?

So I'm trying to recover, and yesterday I said "If I feel hungry, I should eat until I'm full" so I ate breakfast,lunch,dinner,snacks yesterday, but the problem is that it totalled 928 calories only, and I was actually happy because I managed to eat that amount in 1 whole day. Not that it's too much, it's too little, I'm aware of that. But then I couldn't sleep for the whole night, and I woke up at 6.30 am with hunger pangs! so after 30 minutes or so when I finally gave up and realized there would be no way to get back to sleep, I weighed myself and saw that I hadn't lost anything, I got frustrated and was like "F*ck it" so I ate, and was like really hungry :/ I consumed like 2000 calories. I don't know why my body does this to me though, like I get pale and dizzy and it feels like I haven't eaten for days if I don't get the right amount of food for 12 - 24 hours. So after I had consumed 2000 calories, I said I wouldn't eat until tomorrow, 6 hours later I binged on cookies :/ so THEN I purged! and THEN on top of that I took 1 bag of laxative powder. I don't want to do this anymore, it's enough! I want to like my body and I'm tired of being in auto-mode while this other unknown person inside of me is doing this. Please help, I know I can beat this on my own, but I just need some support from some people that have gone through the same! :(
