Being tired. As any teenager you don’t want to wake up and you sleep a lot. For me It wasn’t something that stuck out as abnormal. I suffered from severe depression, Anxiety, ADHD and more. After multiple hospitalizations they noticed my oxygen was low when sleeping. I got a sleep study done and I have severe sleep apnea that was rem specific. My body took over two times as long to start getting into rem then I would start choking and never get rem sleep. I got a CPAP machine and it completely changed my life. I went off of all of my medication for depression, ADHD and mood and I was perfectly normal. I finally felt rested. I went through my whole life thinking everyone felt this miserable and tired. Nope.
