I can't wait forever

Since I'm not a highschooler anymore, Im getting confused about myself. Am I mature enough as my age? I mean. Im always afraid of growing up. What I will face in nearly time is absolutely will be taken aback from what I expected. I'll be in totally different ambience of different people. It kinda scares me off. Will I still be able to do and wear stuffs like I used to? this adaptation might be a long journey. But Im excited. It's not just excitement of being an adult, but also the things that growing up people use to do. Im still confused about the growing up things. I think facing many situations and responding of its problem are the some of the part of growing up. still, Am I on the way to be the grown up girl? Ooopsy, should we call the grown up as women and men? Not the grown up girls and boys? :P
