Constantly feel like I'm doing everything wrong

I have a 9 day old baby. All I do is cry. I never thought it would be like this. I get anxious when I have to take care of her by myself. I constantly feel like I'm doing everything wrong and feel like im always hurting her. I feel guilty for pumping sometimes instead of breastfeeding. I feel like I don't hold her correctly, I don't change her diaper fast enough. My husband is deployed and he hasn't met her yet. His daughter deserves better. I'm just at a total loss.
