Am I the only one?

I am 31 weeks and 3 days. At the beginning of my pregnancy, I had mini panic attacks, thinking "can I do this? Can I really bring a child into this world and be a mom?" We sorta planned this baby. We weren't trying but not preventing anything because of the health issues we had, we didn't know we could have kids. Well, now I'm less than 9 weeks away from my due date and I'm back to having the mini panic attacks. I'm not scared of labour, I'm just scared that I can't do this. That I can't be a good mom. I see how my sisters are with their kids, and I don't want to be like them.. My life is going to be so different with a baby in it, and I'm not sure I could do it.... My husband is a class a apprentice (mechanic) and he's gone from 7 am until 6 at the latest, and when he comes home, he either goes to play video games or wants to sleep.. I don't know if I could do this on my own either. He expects me to stay home, clean, and cook for him when he gets home... It's like, me being pregnant and having a baby automatically makes me a prisoner of my own home.... 
Sorry for the long rant lol
