They want to get out, and you want them out. They are already hunting, gathering, marrying or apprenticing. They are adults in the eyes of all.

But our society has changed so much, that there is no way to really thrive if you are leave your parents' house at 13-15.

If this is the problem then the obvious solution is boarding school!

Hormones
Puberty/growth spurts
Sleep cycles out of sync with their schedules--teens would often naturally go to bed later and sleep in more, but MS and HS starts pretty early. Add that they just aren't getting enough sleep because they are up late with activities and homework and whatnot and still having to get up early, and you've got tired, cranky kids.
Pressure--anxiety, identity issues, making a transition from being a kid to being an adult.

Constant horniness.

And simultaneously the inability to constantly masturbate.

This sounds like the definition of grumpy and rude.

Trying to figure out how to assert independence. An important task - but sooo annoying when you are the authority figure
