Do yall ever look at your past self and cringe hard? Like I am turning 20 tommorow and I was reading through my answers on mangago forums from 2 years ago and they are so embarrassing

Usually my grandma cooks up something. I usually buy myself a cake because my mom thinks it’s too expensive.

Then the rest of the day I dwell on getting older ...

I'm 16 and feel like 60 already. It's going on for 3-4 years so I refuse to believe it's all puberty like they made out to be, if it really was, I'd regret being born.
Will this improve or should I set my sights on a rest home that'll take me in?

I keep reading so many stories where if the guy is over 26 he's being called old especially 30.. I don't get it, to me it's still considered young being 20's or early 30's. Is this a japanese culture?
