Its called reminiscing guys. Everyone is uncomfortable by what they did years back and it doesn't really go away as time goes by.
That's not as generally true as you think it is (I hope). I kept a diary when I was fifteen, and although there are a handful of passages that make me squirm, on the whole I'm proud of my fifteen-year-old self. We'll see whether I feel the same way in 2022, I guess.

They say I'm just scared. Yes, I am scared. But that doesn't mean I'm wrong.
