gained weight too quickly now eating 1600 a day

My last apt i had weighed in and to my horror i gained 32 pounds in 21 weeks. That means i ate everything in sight. I kept saying im gonna eat healthy but i would end up binging. I suffer from disordered eating already which makes eating while pregnant hard. I went from 202 to 114 after having my 2nd child by restricting to 200-600 daily it was a very hard time in my life then but then i concieved my third child and got up to 200 pds again by overeating while preggers.i got down to a low weight of 130s before this 4th pregnancy but i binged and restricted alot to maintain that weight.It has been 6 days and ive been literally eating 1550-1650 daily. I feel normal at that amount and trully proud of myself. It is NOT as easy as with a person who does not struggle with eating problems. I honestly do not think i need 2500 calories. I messed my metabolism up so bad by restricting that i gain super fast on 2000.I feel completely satisfied and full.I do not starve myself. I know im actually losing the excess weight i gained. I t is not good for me to be that big. Back problems,gestational diabetes,preclampsia that is my punishment by doing so.Im convinced now i do not need to gain a crap load of weight all over my body to be healthy. So yes ive cut out junk food to maybe 1 serving a day if im craving. Grilling meats,fillin up on salads,veggies,protein,whole grain breads. Im eating light string cheese, raisins,whole grain crackers,tons of fruits,carrot sticks, low fat grahm crackers. 1% milk, 100% juice, water, yogurt, for snacks. Trust me healthier stuff has less cal so you can eat more. If i want pancakes i eat two with sugar free syrup or if i want bacon i bake it not fry it.i feel good about myself at this point and want to continue it. Im in the overweight category at the moment. I gained before i concieved this 4th i was around 140s so do the math im around 170s right now at 5'2. I do not need to gain any.i can safely lose half of what i gained and just be fine. All i need to do is gain baby weight 15-20 pds at most lol ive already done that.I needed to vent about that. It made me feel better. 1600 is my happy meduim right now. Im going to pray i do not restrict after this baby and keep it at 1200 with hr excercise daily.
