It can get worse after school because not having a schedule imposed on you means you're left to your own devices and will often focus too much energy towards the wrong endeavors. Building a routine of healthy habits and sticking to it can make a world of difference.

There's also a tendency to experience a diaspora after, or in the immediate years after, school. Say, your mid-20's or so. That's potentially a big chunk of your support network disappearing from your life.

Exactly. Those coming to diagnosis and support while young stand a chance to be trained and armed for independence, and an adult life of holding one's self to one's own standards (hopefully). For many of us oldsters, being diagnosed later, or only learning about mindfulness and CBT well past our formative years, it's a huge struggle to cobble together habits and a better mindset.
