I've asked the same questions and keep coming up empty when looking for answers.
All I can think is "what is happy" and "what is normal" which I suppose are copouts.
I think being a teenager (or younger person) is hard, with lots of pressures. I also think the brain chemistry that develops around that age can make it a bit wonky at times.
No answers, sorry. If you find the answers, let me know.

I'm actually curious myself, no joke.
