Baby blues

I am 10 days PP. My husband was able to take a week off when our little girl was born. The first 2 days he was home he got called into work and I came undone. At one point he was talking to our neighbor and I got so anxious about him being away from me that I started crying. The rest of the week was amazing because he was with me. I don't want to be away from him or my mom. He returned to work and I started crying as soon as he walked through the door because I was beyond thrilled to see him home. We have an almost 4 year old son and I don't remember me being this emotional and struggling with this after he was born. I'm having a really hard time coping with all of this. Is there anything that has helped anyone in a similar situation?
