I feel this really strong attraction towards someone and I'm losing all my time just fantasizing about him. How do you get over someone quickly? Like stop liking someone?

It feels like love, but I know it isn't, I'm only 17! Also I don't see him regularly so don't know him too well either.

You avoid contact and literally stay busy all the time!

No contact at all, go out with friends, get into sports at school, or find a hobby that will keep you busy. Go work out, go for a walk, clean the house, do your homework.

Mot of all, realize that this is a dead end street, and if it's all you can think about, that's obsession, and not good. Counseling may help as well.

Agree with the others, first there is no fast way, it takes replacing them with activities and plans. The no contact helps, unfriend from Facebook, no message, and try not to see them.

There is no fast way to get over someone, or stop having feelings.Those feelings fade away as quickly as the appeared when you just go about your life and keep doing your thing like you always have. Of course when you just sit and fantasize, they stick around until you change the fantasy, or find something else to do.
