It seems like Andy has post traumatic stress. Let's hope Zander has the understanding to pass along about the pain/fear the doctor brought out unwittingly. That's Andy's greatest damage, by far, and he needs help with that ASAP.
"I wanted to go back to my room and choose a depressing song and play it loud, so everyone could share in my anguish." What a heart-wrenching situation. I'm glad things quickly improved.
Awesome chapter! And, considering the care and attention given to all the previous chapters, there is no way this story is going to end soon. Parker has too much respect for Andy, his story, and us readers to do that.
