My family has mocked me my whole life for being lazy because of my sleep schedule. "The day is wasting," "I've already done xyz before you've had your breakfast," "Gee AlternatePersonMan, it's 11am nice of you to join us." They snicker and shake their heads.
I have kids now and only finally got diagnosed when my daughter struggled with sleep the same way I do. Huge eye opener. I had no idea this was ADHD related until a few months ago. It's crazy how many issues there are that aren't 'focus' specific.
