I was an incredibly angsty teenager, mad at the world and hostile to just about everyone by default. Apathetic, grumpy, and uninterested in physical activity or the things I liked as a preteen.
After having a baby and getting very little sleep for 6 months I recognized some of my old patterns. Turns out, it wasn't just part of being a teen, I was chronically sleep deprived. I was up at 6am most days back then, when I would sleep until 1pm on weekends. I think a lot of teens are unfairly characterized as angry and defiant when they're operating on half or a quarter of the sleep they need.
