I don't mean to imply that you are seeking sympathy and apologize if you think that's what my post communicated. However, I must say that what I wrote and what the individual (KnightWRX) with whom you quoted me wrote, are entirely different things with entirely different tones.
Let me clarify, what I mean to convey is that I'm curious as to what spurred you to pose this question in the first place. I think you would admit that it's not a general question of conversation. Typically those that are pondering the notion of "never having been born" are doing so from a place of deep reflection or personal pain. As a professional therapist I was simply wondering what about your life or circumstances has brought you to the place of pondering such things.
I apologize for grouping your quote in with KnightWRX's. I first attached all three of the quotes in my post because they were related, but obviously my response below you and KnightWRX's quotes was only directed at KnightWRX.
Yep, I know it's not a common type of question. It's definitely due to personal pain. Your idea is correct!
