To most of us, we don't understand this but we're trying. A couple of people on this thread who suffer from GD have very eloquently put forward the case that this is a real disorder, not just a preference. I didn't believe it was until I read this thread.
Up until you arrived and decided to get offended by people taking on board the lived experiences of others on this thread, I felt everyone was learning from each other.
And to be clear, I know plenty of people who suffer from mental illness. They are incredibly strong people who I greatly admire.
