Anxiety/sadness when not holding baby

Hey, so I had my boy on Saturday, and I'm currently really struggling with just putting him down, letting my partner hold him or feed him etc. I get such an empty feeling when he isn't in my arms or sleeping on me, even just sitting by him when he is in his moses basket, all I can think about is how I want him in my arms. Does this feeling go away or die down? It's pretty invasive honestly
