My sisters made my childfree life sound so unfulfilling. How do I stop feeling bad about it?

My (26F) family is very family oriented and children are seen as a necessity. My parents had 4 kids, and most of my aunts and uncles have at least 3.<br><br>I'm the youngest, and the only one in my family who doesn't want kids. My 3 sisters have 7 kids between them. It's a madhouse when we all get together. But they're all so happy with their lives.<br><br>I've just returned from a family vacation, and it's made me feel really bad. My sisters were talking about how having kids enriched their lives. And they made it sound so amazing. How could I be missing out on such an integralPart of life? How am I going to find fulfillment if not with kids?<br><br>I know this is a childfree sub, so I expect a lot of comments telling me how kids are awful. That's not what I want. I want to know how people find fulfillment and live a happy life without kids?<br><br>I feel stupid. I don't know what the problem is with me that i didn't want kids when it's so clearly better to have them.<br><br>I'm not worried about how my life will be when I'm old. I have 2 sisters that live near me, so family won't be an issue then, and my husband has a big family.<br><br>What are the positives of being childfree? How do people find fulfillment?<br><br>**TL;DR:** I just came back from a family vacay and everyone made having kids sound so rewarding. I'm feeling a little empty inside about it all.
