Near the end of high school a teacher said something that really struck me. She said that some people would look back on their high school years as the best time of their life, while others would slam that book shut and never look back. Not the most profound statement, but it really lit up my teenage brain.
High school was a really awkward period for me that was much more stressful than enjoyable. The idea that I could choose to never return to anything like that and have a completely different rest of my life was exhilarating to contemplate.
It turned out to be true. College was much better for me than high school; finishing college and becoming an adult was better than being in school at all. Everyone has different experiences but I doubt mine is all that rare, I think a lot of people have kind of a miserable time in high school before going on to figure out a life they enjoy. This pop culture idolization of the period does seem over the top to me as well.
I have mixed feelings about my teenage years. I wouldn't want to go back, but I can't say that adult life has turned out to be much better, or that I don't miss that time
I'm the opposite. I LOVED high school, and miss those friends dearly. I'm 45, and it has been difficult to find people that I gel with the same way, aside from my wife (who I started dating in high school). I miss being on the basketball team and marching band. I miss many of the teachers. I miss the 90s and no cell phones, and trolling AOL message boards. I miss being able to exist without the fear of having your life recorded, either by phones or government mass surveillance. I miss when it was accepted that Nazis were the bad guys, and Canada wasn't on fire and making the air quality in Chicago horrific every summer.
College was a great experience too, and I made some great friends, but I really focused on graduating in engineering so I slowly became the party-pooper, and in grad school my wife and I moved in together, got married, so it was a completely different life experience. Now my focus is on work and getting my 3 kids into good colleges.
I sometimes dream about being in high school again, or taking my kids back with me to see what life was like pre-cell phones. I wouldn't say that high school was the best part of my life, but it is a chapter I reminisce about and wish I could revisit occasionally.

From my experience, it's possible to hate the high school/college years, but for them to also be comparably less terrible than what comes after, and so to look back at them with a strange kind of longing.
Like someone else in the thread said, they might have been miserable, but they had potential, options, future ambiguity. After a certain point, those narrow and solidify. A miserable past where the future wasn't set feels more glamorous than a miserable present railroaded into a miserable future.
