This story roused so many emotions in me, I'm not sure I can fully articulate everything it made me feel.
It made me remember not really fitting in, having so much (self-unappreciated) creativity, having bouts of activity followed by bouts of inability to get out of bed, and then finding a friend with enough patience and Zen to move me towards a healthier me.
This reads almost like an autobiography which is probably the author's intention. It reminds me of my younger self when often pent up negative energy just flared up from nowhere and it was frustrating because other people couldn't understand what I was struggling with when my life seemed perfectly normal. Nowadays the symptom might be clinically described as mood swing or anxiety disorder. I don't remember how I got through that phase, but certainly not with a help from such an understanding and patient Stefan like Henry has in this story.
