Right now you can't wait to leave. You can't wait for that fresh start, new friends, independence… the list is never-ending. But coming from someone two years removed from high school, please take it all in. Take in those last goofy times in class. All those fun car rides in the middle of the night with your friends where you laugh so hard you cry. Spending all day long with the friends you've known your whole life… remember how it feels in your heart. Enjoy graduation and take lots of pictures. Remember to always remain in the moment during all of these events. Don't let anything ruin it for you. That carefree feeling you have right now and will continue to have this summer will pass whether you believe it or not. Adulthood crawls in quicker than you think…
You will be left with the memories of what was, never to see or speak to so many people you once genuinely had so much fun with. High school is such a unique experience and I believe many of us take it granted because it is a necessity. We look at it as a chore because of mundane things like it being boring and having to wake up so early. In the moment we fail to see how fun it actually was. It is often only afterward that we realize just what we really had in those 4 years. Admittedly, I never thought I missed much of anything about high school, and I especially never thought I would. But here I am, two years later and I'm just realizing how easy I had it. High school was hard, but when I say the real world is harder, please take my words to heart. I am a firm believer that high school, in general, is a massive bubble.
Not to say that the bubble is bad. But the bubble will break, and it's more jarring to some than others. So don't let it impact you in a negative way, be prepared for its impact and conquer it! My point is, know that high school is not supposed to be the best four years of your life, but it is a time of your life where most people have the least worries, and that is something you can't get back. Worries and stress are subjective, so of course, we all thought our lives were over multiple times in high school, but we shortly realized that was not the case.
Your last teenage years should be taken in stride. Don't wish them away for older age, enjoy them. You'll never get them back, so you might as well stay in the moment.
