A Rushed Decision

I just started school about two weeks ago but I now realize how completely wrong I was. For years I've planed to graduate High School a semester early then move back to Ireland maybe travel a but then start at an Irish uni in the fall. That was until I made a mistake on one of my applications for an American school (which wasn't even my first pick) and got accepted for spring semester. So me being so hurried to grow up, leave home and move on decided to go. HUGE MISTAKE. I miss Ireland and its the only place I feel whole/ at home (cheesy I know but it's true). The school I'm at though there is nothing wrong with it, it just so happens to be completely wrong for me as well as the city I am in. It also is nothing like any other colleges because its a huge art school with so much going on but it lacks a campus and a college experience. I also know now that I need a brake from school. Since freshman the longest I've had off school was just over two weeks because of the summer classes I needed in order to graduate early. I also need time to get myself together, start becoming the person I want to be and not who others want me to be.
So that being said I will more then likely take this semester off ( I still can till Saturday without it being on record that i was even ever in school) after like a week of class move back home and become a better me. And probably disappoint people at the same time which is really the only reason I am still questioning it but I just don't think I'm completely ready for college especially one I am not happy at.
