This same thing happened to me in high school (it wasn't as elaborate). I'll spare you the details and say it was devastating. I've never really gotten over it and it stays with me to this day. The feeling of feeling completely alone and then finally having someone notice you, is an incredible feeling. What's truly devastating is having that ripped away from you, everything you knew was a lie, and your back to that point of loneliness, but it's much worse now. This sort of thing can last a lifetime. This is no joke.
Don't believe how serious this is? Google "Ryan Halligan's suicide".
@those who are saying the story is fake: It doesn't matter if it is, or not. It's happened, and it's nothing short of bullying in the cruelest of sense.
