Postpartum separation anxiety?

I’m not sure what’s gotten into me. My son is 9 days old and I will be staying home with him for the first 8 weeks or so before going back to work. I love being home with him and taking care of him even though it’s exhausting sometimes, I’m so thankful.

However, my fiancé didn’t get any time off and works 5 days a week. When he’s gone I get so much more anxious and I cry a lot because I miss him so much. I’ve always missed him when he’s gone but not like this. I’m perfectly capable of being alone and taking care of our baby boy but it’s just so hard on me to be away from him right now and I don’t know why. Has anyone else felt like this? I feel so pathetic 😔
