I feel like a terrible mother

I was giving my two week old son his bath tonight and he choked on some water. It was the scariest moment of my whole entire life he couldn’t breathe and was trying so hard to. I took him right out of the bath and got him to cough it up and called the pediatrician to make sure he was ok but I feel so terrible I feel like an awful mother like I don’t deserve to be his mom. He deserves someone better who won’t hurt him and can take care of him. I want to die thinking about what just happened. I can’t trust anyone with my baby and now I can’t even trust myself 😕
