my fear of growing older

im turning 18 on the 13th and thats so insane to me because it was just march or april so mentally, im not all here rn. im an adult in 2 days and its scaring me so much because the same week i turn 18, is my final week of high school. life is moving way too fast for me cause im so not ready to be a young adult and start a new chapter of my life. forever in my head, im just a teenage girl in high school but obviously at some point, thats gonna have to end... BUT IT ENDS IN 4 DAYS??? thats so wild to me. 18 feels so old and im so sad to see my friends move away to universities in other states. i dont know why but im just not coping well with the idea of getting older. of course im excited to graduate but another month or two wouldnt hurt. i wish i had experienced more things in hs, like joining a club or sport. this is so weird to me, but hey, at least i graduate in 4 days and start something new in my life. n e ways, at least i can do so many things once im 18! ugh i need money for a tattoo and a nose job
