Same! I've been a long-time fan of his, and I don't think he had ever shared that much about his personal health condition. He tended to talk around it before - I had known him to mention that one of the things that gets to him is the sound of a heartbeat, but he avoided going into why... until the end of the Jimmy and the Pulsating Mass series.
The person I pushed to buy it is one of my best friends who was born with a significant disability and had through the past few years gone through a lot of self-discovery and self-transformation into a sort of phoenix persona. There were quite a few times throughout the game I'd thought of them, so I absolutely had to show it to them.
