Post partum prevention

1st baby is here! Born on 9/11 at 1159pm! 7lbs 10oz! Hes one week old now and I still cant believe hes here. So many emotions and feelings that I'm trying to understand as my baby and I get to know each other. I had so much anxiety 1st few days it was so stressful but it's gotten better. I'm enjoying it a little more now. Mom is here helping for the week but she will be gone next week and I'm afraid I will get so lonely during the day by myself with the baby everyday while hubby is at work. What are some things yall have done/are doing to prevent post partum. I still cry a little from having given up in breast feeding and I get anxiety from thoughts like, I just got my baby and I'm so afraid I'll lose him now.
