His expression of emotion is harder to tell. Often you can't tell except he paces back and forth yelling about something he's excited about and doing a thing with his hands. Staying up for days, getting overwhelmed by all the day to day noises and having more meltdowns.

His depression is quiet but deep. He picks at his skin and continues well after it bleeds. Thinks very negative thoughts about him self. He'll tap "I love you" often. He's really quiet and stares off into space a lot when depressed.
