Girl Crazy! What Should I do???

What should I do? There's this girl at school that I am In Love with! I am completly obsessed with her. and i would do anything for her. But She doesn't love me back, and It's killing me! I'm completly obsessed with her. I even choose what i want to eat based on what she likes. One time, another boy asked her out, and I thought she said yes. Well, I want in my bathroom, and chocked myself until i passed out. and It turns out that she didn't go out with him, but still. My grades are falling because of her, My personality has changed because of her. and she is my only motavation! I love her so much! I know I need to get over her, but I can't! I've tried everything to get over her! But I just keep loving her even more! What should I do???? It's killing me! I haven't eaten or drank in 3 days because I'm so stressed because of her.

A love story can only occur when two people choose each other. You will have to accept, that she does not want to be your girlfriend. See a psychotherapist if possible.

You will have to accept reality. You cannot force a girl to love you. You have to respect her wishes.

This resembles stalking. See a psychotherapist.

Sorry about stalking, but see a psychotherapist anyway.
