As much as I dislike raven , I have to agree with him here. Back when I was your age I thought I was in love with this one girl, and basically I'm sure the same thing happened to me that happened to you. It'll pass soon enough, hell, I nearly went insane once my fiancee and I broke up, I still get furious when I think that I can't see my kid everyday etc.
But itll pass bro, I wouldn't advise getting homeschool because of this, you shouldn't try to run from things like these, especially at your age, what happens is when you get older and confront a real problem youll try to run from it too.
Anywho, hope you feel better bro.
