Help me :'( please ...?

Hello I'm 13 and 5'9... And weigh 8.4stone that's like 116 lb around and model ..

So my story begins when I was 9 I was already concerned about my weight and my appearance I started shaving when I was six (my legs) and I wore makeup everyday from the age 9 and I had. A gym ball and running machine for Christmas~ I dieted even then + exercise

So when I was 11 being as sensitive as ever about my weight somebody called me fat; so Cut a long story short I starved myself for 5 days + compulsive exercise Collapsing as I worked out for 2.5 hours every night 5 hours at weekends .... Until I collapsed at school and they phoned home n my secretive days were over~they said I needed counselling but I put up a fuss and refused to go because it made me feel like I was retarded and I didt like that feeling. I was convinced I would sort it out by myself....

Few months later I passed out with pain in my abdomen ...from then on the same sharp pain in my stomach put me in and out of hospital for 3 months;it was gallstones three golf ball sized balls in my gallbladder that in the end burst my gallbladder and were free in my body and I had to have an operation a day before my twelfth birthday. I lost 1 n a bit stone Going down to 7 stone

Once I had recovered the normality began again and this time I had a new weapon~ Acai pills with more exercise and food plans having 900 calories a day with strict times of eating and what it was ...

Then I went on holiday and found some older lads that thought I looked 16 very happy memory;but all the food and the guilt of hardly exercising soon kicked in and I made myself sick I said just once but it happened again and again and again+ worked out for 3 hours a day I had even brought my DVD with me .... I said ambs you workout n binge for these two weeks then it stops.2 weeks later I got home.

I still continued to binge when I got home+exersice+ food intake reduced+Acai pills ... 6 months down the line still do all the stuff ...PLEASE HELP ME
