time is moving so fast

hey to all nobodys out there!
I just realized that time is really moving soooo fast, meaning my time at school is nearly over for good. You may think this is a great thing, though I´m not sure about it, I have to admit.
Thinking of all the bad things(teachers, tests, anger, stress, dirty toilets, childoverflowing corridors.....) I´d definetly say "heck yeah! finally we are able to move on into adulthood!"...But then again school is also one of the most exciting things in my life, I´m not kidding. One thinks he has to got there but imagine a day without gossiping seeing your mates or having a laugh over one mad teacher...Although I´, really looking forward to my time as a student there´s still this nudging in my head saying, time is gonna pass and you´re gonna miss school either way...I´m thinking about studying abroad so I´d be all alone exploring the great outdoors:D...
Ít´s all quite a lot at the moment thinking about what to study and where, I mean how am i supposed to know what´s really right for ME?..I´m I really a potential journalist or rather a politician...is it wrong to exclude all sciences just because I dropped them a few years ago?...Problem is there´s nobody answering all these questions cause it´s me having to figure this all out...Well then that´s what I´m going to do love xoxo and have a good nights sleep!
