Hi, sweetie. My sis couldn't have children, so I can say she's had some of the same symptoms. Children are nice, but they do create more problems, plus are expensive. I was happy without and with children. People do associate children and Christmas too much.
I'm so sorry mean things have been said to you.
Have you considered fostering a child?
Or even babysitting? That way you can enjoy children and then send them home, like grandparents can do.
