Please don't cross into internet psychiatric diagnosis on HN. Even though your intentions are good, comments like this are more likely to land as personal attacks than anything supportive.
I've often encountered people who've told me that my desire to not have children is immoral in some way; that I'm being selfish. It's not a perspective I agree with at all, and I know several other people with kids (that they wanted to have) tell me there is nothing wrong with not wanting kids.
I've heard people make a moral case for having children, but I've never heard people implying others are mentally ill for not wanting them.
It does get into deeper questions about what are mental illnesses; how some illnesses warp our perception and cause delusions, but others are just things we've socially evolved to think as unacceptable because they cause harm. Homosexuality was once a mental illness, and now it's not.
Maybe if Earth's population takes a big hit and we're under 1 billion again, I could see some case to be made for society to adopt procreation above all else; but today .. we've moved past that .. and I agree; not wanting children or regretting having children is not a mental illness at all!
