Do you think i could have Anorexia nervosa?

Im nearly 14 and weigh 8 stone and im 5'4, i always feel fat, and try not to eat when im hungry i only eat when my mum makes me and even then i only eat a little. iv search the symptoms and i have quite alot i loose my hair very easily, i have bad mood swings, i feel tired easily, i ignore my self when im hungry, i feel depressed, im very concerned about being over weight, i will count most of y calories i don't go over 1500 but when i do i feel so horrible and so fat, i have very low self esteem, i love swimming but wont go because of my body, i don't like eating in front of people because i think there watching me, i really want to have a perfect body and will do what ever to get it, i used to be addicted to exercise but i don't do it anymore because i walk everywhere i go, i always look in the mirror to see if iv lost weight but never have and i always weigh myself hoping iv lost weight, sometimes i binge eat, then try and make myself sick but it hardly works, i have self harmed myself before as well xxxxxx
