460 calories a day

Hi i am an 18 year old girl roughly 5ft10 to 5ft11 and my bmi is within normal range. I really hate my body but i've never really had any problems with eating in the past except becoming ectreemly intolerrent to nuts over night lol
Recently i have become very obsessed with calories and its never bothered me before. I am currently consuming on average 460 calories a day. I know this is bad and i know the risks so i don't know why i am doing this !!!
I can't eat anything unless i have measured it out on scales first. like today i ate ready break and it said one serving 30g but it came to 32 and i HAD to take off the extra and finally settled on 28g. I had a glass of milk but i measured it in a jug so that i new exactly how much calories i had. I am currently exercising quite a lot and i am at uni all day and then going up to the stables and riding in the evening. I know that this is bad but it makes me feel so good and happy. This literally happend over night and has only been going on for about a week. I am rapidly loosing weight already but i heard that this is water weight which will return pluss more. I am drinking a normal amount of water yet my throat feels constantly dry. Before this my weight has been very steady. I am getting really irritable around people eating and feel angry yet i am not really craving food. I know this is very early but i already feel like i am getting sucked into it. How much longer will this sustain me ?

can you try not measuring food?

maybe focusing your obessive/compulsive behavior on something else like if its organic or not and free of pesticides/fungicides/herbicides/antibiotics/growth hormones...im not trying to joke or be sarcastic but to offer an alernative for your pathology...

eat healthy! eat organic! eat local!

good luck
peace be
love free

You are on the path to anorexia. If you keep this up you will stop menstruating. If you still keep it up your family will put you in the hospital. I don't understand anorexia because the girls subject to it get so thin that they lose all the curves that make them female and they become  - ugly. Yes, ugly. Think about it. Are you rejecting your femaleness? Are you rejecting men and sexuality? You say you are not hungry. But you are not hungry for a reason that has nothing to do with food. You are purpoely destroying yourself. You have to find out why.
