If the thought of having baby freaks you out, does that mean you're not ready?

I'm 31, my plan as to start trying in a year. Not sure about my partner's exact plan, I have a feeling he might want to start trying earlier. He just talked to his friends, they all either have a baby or are pregnant. They were talking about how difficult it is to get them to sleep and how sleep deprived they are. Now I'm freaking out. I don't deal well with being sleep deprived. My upbringing was terrible, with lots of abuse, what if I will continue the cycle? I'm already struggling keeping up with technology, how would I keep them safe from negative influences? I've suffered from bulimia, I'm better now but how will I teach them a healthy relationship with food. Or healthy self-esteem when my confidence is non-existant. I just don't think I'm cut out to be a mum.

Is that normal to have these thoughts or does it mean I'm not ready. Seeing as I'm not ready now, I probably won't be in time, but my partner really loves kids. It would be unfair for me to stay with him
