How to hate this girl ?

Hate is a terrible emotion and you should never hate anyone. I think you should work on feeling better about yourself, if you think you are overweight then do something about it...lose the extra pounds. Also work on your self confidence and look for a girlfriend you can have some fun with and stop obsessing about this girl. You sound like a very nice guy to me and hopefully this has helped a little.

Like someone said, she will slowly start to fade in your mind with time. You have to be patient, it takes time to get over a crush you've liked. Since you think she is the most beautiful girl in the world lol.

But move on, she is not worth it, she should be your last concern.

Haha I understand what you said.. I'm brazilian and my english is bad..

I know what you feel, is very boring because you can't control you heart, I don't know how I can help you, but i know of one thing: You don't wanna forget her, you said this because she rejected you, and now you are nervous and want forget her. What you can do is study, you're young and will find many girls in your life.

Maybe, she reject you because she don't like you. You do bad in try impress her.. Naturally you will forgot her.

Sorry if you don't understand something that i said.. My english is not very good...

Good luck guy!!

you don't wont to hate anyone, because that takes up so much of your time also. you can through yourself at her, and force her to do something about it. or you can go to concealing to get help.life can be hard and sometimes we need an expert's help.

If it makes you feel any better, she actually gave a bj to all your friends buddy.

She will fade slowly. Don't worry. Or you can make another attempt to get her. :)
