"You're so mature for your age" was never a compliment.
Every time I heard "you're so mature for your age" as a kid, I thought it was a compliment. Now I realize it was a red flag. I wasn't mature; I was parentified. I was forced to grow up too fast because my parents couldn't handle their own emotions.
I learned to read the room, manage their moods, and suppress my own needs to keep the peace. That's not maturity; that's survival. Now I'm an adult who struggles to ask for help, feels guilty for having needs, and panics when things are too calm. If you were "mature for your age," you were probably just a kid who wasn't allowed to be a kid. I'm sorry you had to grow up so fast.
