Thank you! Sometimes it seems like those who have children just want to feel superior to everyone who doesn't.
When I was married, there was the possibility at any time that I could go from 0 children to 2 or 3 or even 6 children I could be responsible for, and I had nightmares about it for a year. But I did what it took to be prepared for that possibility. Thankfully, it didn't happen.
Yet, the "selfish" and "immature" labels still continue to be thrown at people in my situation. Among other things I did, I had raised over $46 million just for children's charities in my career. I know, that doesn't count. Giving to those who have children just doesn't count, because they just expect it. "God said so."
They don't have "Aunt's/Uncle's Day" or "Single People's Day" or any kind of celebrations of life for childless people. We don't even get to have birthdays in my family. Do you know how it feels to be a non-entity?
I feel much the same way as you, but I have 3 kids. I felt like a nobody because of a "design flaw" in my body I am unable to produce breast milk. You should have heard the comments and seen the sneers of the breast feeding do gooders. It's a superiority complex. No matter what your lot in life some people just make you feel crappy. The thin make fun of the fat, the childbearers the non child bearers, northerners vs southerners. It's just life. Happiness and fulfillment come from loving yourself inspite of others. I hope that your charity work has given you a lifetime of fulfillment. I think it's wonderful.
