What can i do? im really depressed about my last day of high school?

awww high school... i'll tell you this: everything you are feeling is completely normal and it's just how I felt when I was graduating. I hated my freshman year but things got better. I never had your "blissful high school years" as they portray on TV - never got popular overnight nor scored a record, nor got the cute guy but on the last few days before graduation... i don't know... it just got sad. Suddenly, my world that was so comfortable and that I had just adapted to is going to change. You have mixed emotions - happy to graduate and do real world things, opportunities, etc... but you're sad and can't believe how fast time went by. I'll never forget what my principal told us on our last night together (as a class), "they say high school will be the best years of your life but they're wrong. it's the beginning of the best years you'll have. once you go out in the real world, you'll only continue to make better memories." And that's what made things clear
