Should I stay should I go? Oh I really don't know

So I'm faced with a difficult decision. I have lived where I am now for 8 years and believe it or not I actually made friends. But there's this high school I've always wanted to go to. It was one of those little dreams you had but never fullfiled but now my parents are letting me make a decision: Go to the high school of my faraway dreams or stay at my home.. With my friends... And familiarality..
