One specific challenge of raising adolescents is I think precisely running into that place where they start to hit the life confusions you're speaking of, and it's in many cases like holding up a mirror to your own pains from adolescence. But this time without any agency, you're a spectator.
When they're little and they're reaching for a hot surface you can raise alarm and grab their hand and pull it away.
But you lose the ability to substantially "make" a young adult do anything. You can't stop them from skipping school. From spending all their time on their phone. From smoking weed or wasting their time on video games. Or much worse, harming themselves in any number of scary permanent ways.
You can't pull their hand away from the fire. They have the autonomy to make mistakes and something about that age... some just seem to revel in it?
