I don't like the overly-personal, almost condescending and childish tone. Why not just write normally? I can discuss and explore my feelings without being spoken to as though I'm on the edge of a mental breakdown and one strong word would push me over. I don't need to be told "good job!" for scrolling to the right or selecting a colour.
Everyone on HN will appreciate clear, concise documentation and instructions in their day jobs. I don't see why mental health discussions should be any different. Imagine if Python docs were presented in this style.
