As of this month, I am officially 19 years old, and it is crazy that my time as a teenager is almost over. It seems like just yesterday I was a 13-year-old with bright blue braces, obsessed with Doctor Who, and learning how to put on mascara for the first time. But despite the inevitable awkwardness that comes with being 13, I love the girl I was then. And I am especially in love with how I grew and changed into the girl I am now- a 19-year old who forgets to wear her retainers, is obsessed with Rex Orange County, and is learning how to be an adult for the first time. Every year of life means a whole year of learning new things about the world, other people, and yourself, which is just so, so beautiful.
