What to do about jealousy of my friend?

My good friend since 7th grade,Christine has been through everything with me.I love her to death and all,but this is the thing - I'm jealous of her sometimes.She's a beautiful girl.She's tall,thin and has the perfect body,though she thinks different.She thinks that she needs to lose weight,though I know that she has a nice body.Anyways,so I don't know what to do.

If I were to put myself in words,I would say that I'm mostly considered, 'The Chubby Friend,' which I absolutely hate to hear!Most guys like her,and I've never even had a boyfriend before.A lot of people think she's pretty,some people don't say much about me in that department.You know - I feel so left out.Call me a weirdo,but sometimes,it makes me want to cry.

Sometimes,I just want to me takened more serious by guys,and so forth.I have my friends,and they love me for who I am,but sometimes,I can honestly say that I look at some other girls and think,You know - I wish I was just like them.

I've been chubby for most of my life,which I can't take anymore.My mom says that I'll become thinner as I get older,and that I'll grow taller,and so forth,but I'm fifteen,and I barely notice a difference sometimes.I just want to be pretty just like my friend.

What should I do?

wow reminds me a lot of me except its a bit backwards for me... im the chubyish one but guys like me.. and my friend is tall and skinny but never had boyfriend ANYWAYS

I dont want to be rude.. im chubbyish too though so.
maybe you could try to lose weight... might help you gain confidence which guys really like

First Step - think positive.

I'm not saying be all like 'I'm the best, everybody loves me' etc. But don't put yourself down. Build your confidence, people tend to lean towards confident people.

Not all guys consider thin & tall to be pretty, I know quite a few 'larger', chubby girls who have had many boyfriends.
