How can I regain my confidence and self-esteem?

SO lets start in 3rd. In 3rd I was healthy,funny, confident,adventurous,thin. But then I moved at the end of the year. In 4th grade I was healthy until my parents got divorced and I started using food as my friend. Then in fifth grade I swear I gained like 20 pounds!in two years =C.Then in sixth I starved myself trying to be anorexic. Its sad because I was super weak I almost didn;t have enough stregnth to eat it took me like 2 hours to eat. In may I fractured my arm so I have lost my adventerous side =C. Then in the summer my dad told me I was going to another school. And my mom also left me that year(no she didn't die she left). When I first went to that school I felt lonely and depressed so I cut my self with scissors =C. But later that month my friend saw'll my arm and she was like are you emo? I said no(but I was depressed). Thats what made me cut less. In my school there are no mirrors on the 7th grade side so I cant see myself. So when im at school I feel like a monster and obese. but im just slightly over weight. SO one day I went to chilli's and I felt like I had eaten to much so I made myself puke. I am usually a strong person but sometimes I feel so much like crap I do the worst things to myself. Then like two days ago I ate ham and squash and I was in the batheroom making myself puke again. I am pretty sure I will do it again so what do I do? How do I regain my confidence and self esteem and maybe my adverterous side?

People will like you for who you are, my best friend is big and everyone loves her! just have a great personality, get back on track and then maybe hit the gym with some friends and talk it out. You can eat like crap if you excersize well. Explain to your friend you are not emo. Really, not everyone is emo for cutting. I used to cut but I too was depressed I didnt dress in black or anything like that. Good luck!

when I'm mad/depressd I go to the gym work out so much I feel like ima die then I kill the punching bag to relce anger

try to look in your self in the mirror and and think of good things about your self try being stuck up and you will eventually feel better

believe in your self,don't ever look down at yourself.the most important thing in life is what you say to your yourself; wake up look into the mirrror and see the cute,adorable person who is full of life,who has what it takes and tell yourself I am beautiful,confient and I can do it...take a bath,look good and step out with a smile on your face,smilimg from the inner most part of u,don't bother yourself about what anyone thinks of you because you are you and they can never have that vibrant life and fufillment u;ve got...the sky is your limit live life,believe,proclaim and act...

try not to be so depressed and honestly(im not just saying it because its doing the right thing) cutting yourself really doesn't solve anything
if you want to lose weight dont threw up or stop eating
start eating healthy and start exercising,that should help you lose weight and maybe being healthier should boost up your confidence and your "adventuruos" side also

good luck and stay positive
if you need somebody to talk to just leave me messages and ill try to reply as soon as possible
