Falling asleep with baby on your chest

Has anyone else fallen asleep whilst your baby is laying on your chest at night comforting them back to sleep? The last week has been non stop during the night and I’m running on empty and I’ve just fallen asleep with baby on me for half hour. I’ve got a camera on us and you can see that any movement she made I checked on her. But now she’s back in her bed I can’t sleep with paranoia. I’m running on nothing. I try to use my phone during these times but I literally had nothing in me to stay awake. I feel awful.
