When Did I Stop Being Me?

Hey, so I've been thinking a lot lately about how much high school sucked for me. Everyone was trying to fit in and be cool, you know? Like, we'd all laugh at someone who wore the wrong shoes or didn't have the right brand of phone. But here's the thing: one day, I just realized that my 'cool' friends were only cool because they copied what everyone else did. It was like a big joke and I kind of played along too, you know? But now when I look back at photos from those days, it feels weird and fake. What am I supposed to do about the part of me that just went along with all that nonsense? Am I still that person inside or is there hope for becoming someone better?
