I have some experience with this as I have delayed sleep phase disorder. My pre-college school experience was bad, intolerable actually. I never could fall asleep until around 1AM, I just did not fall asleep; but, Id have to wake up at 6AM to get to school on time. As a result, every day was a struggle. I failed most of my classes and had behavioral issues. Of course, this was my “personality” or so I was told, so I was lead to believe I was not a very capable person while growing up. Eventually, I developed anxiety and dropped out of high-school. Skipping ahead… It took a little time for me to build up the confidence to return to school (a couple of years), because I thought of myself as a failure incapable of doing well academically. It turns out though, I just needed sleep. Imagine that. The guidance counselor who thought Id be lucky to find a trade job, the psychologists who thought I was psychotic, my parents who thought I was a failure, were all wrong. Sleep deprivation is powerful and because I did not maintain a “normal” sleep cycle, it pretty much ruined my childhood. Oh well. Now that Ive left the restrictive system and now that I can control my schedule and get the sleep that I need, Im the “model student.” No behavioral issues and a 4.0 GPA. Crazy, right?
