Calorie needs? Confused.

I didn't lose when I ate about 1600 does this mean it's my maintenance? I also didn't gain eating 1800 and occasionally 2000. Would I gain eating 2300? Like proper weight? Not "food in my body" weight.

unfortunately, no one can tell you the answer. you HAVE to try and find out for yourself. people can say what worked for them but EVERYONE is very different. try eating 2300 for a month and see how much real weight you can. in a month you should be able to put on 4-10 pounds easily

Could someone suggest me my calorie intake for maintenance AND weight gain?

I'm 157-158cm, 90 pounds.

Through mid jan to mid feb I ate about 3500~4500 calories while under-estimating intake :D and got myself up from 72.6 pounds wow. Anyway, since mid-feb till now I've been eating really weirdly, can't figure out how to eat which sounds absolutely ridiculous as it should be the easiest thing to do. Anyway, yeah so calorie intakes please? Oh and I'm a fifteen year old, I think I'm sedentary because I go to school by car, travel everywhere by car basically and only walk around for classes at school and then at home I'm usuall sitting on my bed with the laptop on my lap on this website and then the occasional trip down stairs to get food.

Oh another question, help me eeep. I can't stop eating after school. I eat way past the point of being full then I feel like I'm gonna throw up and it's hard to eat dinner. Ugh.

try eating more through-out the day. pack a huge lunch to school and eat it all before you get home. then you should be normally hungry by dinner and then have a snack before bed... but you should be getting at least 2500 if you want to gain but you should be doing 3000. 3500-4500 is probably better cuz the faster you gain the weight the faster the recovery... the binging is normal though. your body is still starving so it just wants all the food it can get at one time,. what do you normally eat during the day? like, what do you eat leading up to when you get home normally? also, learning how to eat is VERY hard and in my experience is taking the longest to figure out over anything to do with this ED. learning how to eat normally is NOT EASY AT ALL! just try to listen to your body and eat when it feels right to eat. its hard when ur recovering cuz u have to eat an unatural amount of food (eating an excess amount of calories so you can gain weight). i assume it will be easier to eat normal when ur at a healthy weight...and it would come naturally.
