I hit puberty when I was 9 years old, it was not fun at all.
I have a friend who hit puberty at age eight, poor thing. But by the time other girls reached that point, she was already used to it. (Found out about this during one of our "girl talks" that came up randomly and awkwardly.)
I started when I got into middle school, but mom had told me a little about it by that time, so I was slightly alright (I was shaking, but I at least knew what it was thanks to my cousin, who had gotten it about a year earlier). I was then taught to be quiet about it, though I've slipped it out about a couple of times since then anyway. And at the end of... eighth grade (I believe), I found out I had pit hair because a friend was teasing me about it in middle of a speech my art teacher was giving us. Yup
. I think the guys were cool about it, but I dunno.
I've had somewhat bad acne, but not too terrible (except for the pus-filled ones, I had one on the tip of my nose in ninth grade). I've been taking care of it for a while now, and my face stays clear as long as I use this... cream treatment thingy... It works wonders.
As for growing, I think I'm done until I'm 18. I'll forever be a midget x3.
I've kinda noticed that though girls have a higher voice than men, it seems to slightly deepen a little than from when you're a kid. But I don't know. As far as I know, I've sounded the same since I was ten.
