First day alone with baby

Tomorrow (technically today since it's 1am) is my first day alone since we came home from the hospital. My boyfriends work originally told him to take as much time as needed and he was going to take tomorrow off but they asked him today to come in tomorrow. He and I are both pretty upset about it, and I'm super anxious. Even with him home it's been hard to do anything since we breastfeed. I know that I shouldn't complain and I should be thankful that he had any time off with me but I'm not sure how I'll do without him :/
