I know you think it's a big deal, and well, yes, you should celebrate it. But for the most part, things are still the same and change is yet to come. You will wake up still with acne scars. You will wake up still with painful memories carved into your thighs. You will remember that once it wasn't like this and you will have the vague sense that even what you have now will soon no longer be.
Rejoice in the fleeting nature of this moment, with its infinitesimal relevance and infinite beauty. You live here in this ever-changing space; nothing stays the same and you let yourself be carried from day to day. You drift. You watch the landscape of your heart slowly change. Sometimes the sun is creeping over the horizon and the sky is painted in your favorite colors. Sometimes you watch the sky shed tears and apologize for its mistakes. Sometimes you feel filled up with it.
You're turning eighteen. You're scared. And no, you will not wake up entirely different. You will have to keep being alive without knowing what it means. You will still have to be alone. This is your body. This is your soul. This is your brain; these are the demons you've created, monsters you've fed. This is your heart; these are the cracks, these are the bruises which are still tender, still blue.
If you listen closely, it is still in pain, fighting to beat each second. It remembers how you kicked and screamed and threatened to hit it, beat it to a ****** pulp, if it refused to give up on its own, to just stop, to pack its bags and leave behind a sunken, shriveled mess. You remember you were wearing tennis shoes and holding a baseball bat.
Sometimes, inside you, there are thunderstorms no one can tell are brewing. It's just the weather. Tell yourself that. It's something you will have to put up with and make adjustments for every day of your life. So pack an umbrella, buy pink rain boots and a matching polka dot rain coat, if you want. Bandage your heart better, prop it up with stilts, and whisper good things to it sometimes.
