I'm so scared that I'll change my mind

You know, these women who hate children and love their freedom, then change their mind in their 30s and have a baby. There's nothing wrong with that, but I'm so scared it'll happen to me. I love my carefree life and having a whole family and kids is my biggest nightmare. I hate the thought that I might succumb and become one of those always tired moms posting memes about how they sacrificed their life for a kid.. because of some hormones? I know what happened to my mom and I feel like those people are just coping. I'm just scared to become one of them
