Husband goes back to work

My husband is going back to work tomorrow after being off for 14 days with me and baby. He works 12 hour night shifts and I don’t know how I’m gonna manage the baby, the animals, and the household all by myself. I feel anxious and extremely overwhelmed already. I can’t even imagine when he goes back tomorrow and baby/pets/house will solely rely on me. He was of great help providing me with food and care during this time. He helped with baby and the house. How do women do it?! 😞
