Why am i like this!

So I have a 4.5 month old daughter and tonight is the first night she is sleeping in her nursery instead of cosleeping. I havent slept at all. Not even one hour. Its 3:16 and every 30 minutes i am in her room hovering over her making sure she is okay. I have to wake up for the day in 3 hours because our dog is getting fixed this morning and drop off is at 8 AM. We will have to leave the house by 7:30. So I have to wake up at 6:30 to feed the baby, get her changed and dressed, bathe the dog and drive all the way across town for her surgery. Thank goodness my husband is off tomorrow because i am going to need a nap more than ever!
