I totally understand not wanting to have children for disability and deciding you are not fit to be a parent. But the OP had a lot of projection onto people who do have kids, which is false. I think being 100% financially able to have children, and choosing not to because you like to travel and watch Netflix more, is a poor reason. But everyone is free to make their own choices.

My point about being comfy, was the OP's self description of a blessed, wealthy, pain-free life. But this state of things is temporary, so to be sure one has the mental, emotional, and spiritual tools to accept life when one isn't living a comfy existence. The description of having kids, and of life itself being meaningless, is a signal that when life throws the OP a tragedy, the response will not be healthy.
