Self-conscious😑

Okay, so I'm a 16 year old female and I completely hate my body! Tbh I used  to be so happy in my own skin (where I used to live) but then I moved to s different area and I constantly got bullied about my figure. I began to cut down on eating and opted for dieting, but nothing I did stopped the bullying so I stopped eating. My parents found out because I became really ill and skinny (admittedly I looked disgustingly sick). They forced me to eat and when I was at school they had members off staff supervising me eat. However, I was laughed at by the people who were bullying me, and I got told if I kept eating as much as I do I'm going to be the fattest person in the school (at this point I looked anorexic anyway) so with my "not eating method" failing I chose to make my self sick after meals when I eventually had time to my self. Anyway we ended up moving in the end and I finally managed to build my weight from a tiny 'age 6-7 yrs' up to a  healthy size 10. (Age 15)... However during the past 8 months my weight has somehow deteriorated down to a size 6. I'm so annoyed and feel disgusted in myself because I didn't notice. It was my nana that pointed it out then my stepmom agreed with her. Yes I often skip meals but I've been trying so hard to build my weight up, sometimes it just feels like it's too much😑
