Scared shitless of becoming a mama

In the last 2 weeks I’ve been so emotional and I’m so scared to become a mom. I’m not scared about birth, I’m scared about the life change and screwing my baby up and the responsibilities that come with it. This pregnancy was totally planned but I keep questioning if we did the right thing. My husband is super supportive and keeps reminding me of how much we both wanted kids. I always thought I would have kids and couldn’t imagine my life without them. I still do want them but I’m just scared. My husband and I have a great life and I’m so scared it’s going to change for the worst.

Please no judgment I’m just having a lot of anxiety about being a new mom
