I feel like complete shit and cant stop worrying, crying and feeling so bad.

I co-sleep with my almost 4 month old. Last night when she woke to feed I don't remember picking her up and feeding her, but I was woken up by her cry and before my mind could even process what was going on I was picking her up off the floor! Apparently I was feeding her, I must have been half asleep/awake and she fell out of my arms onto the floor. (Out of my bed)☹

After I picked her up I instantly checked her all over, she stopped crying and took the rest of her bottle and fell asleep. I was so concerned for her going back to sleep incase of a concussion. I stayed awake almost the rest of the night watching her sleep just incase. Moving her arms and legs to see if it hurt and to see her move in her sleep.

Today she has been acting completely like herself. Cooing, laughing, eating, playing. There's no bruises or bumps or scratches or anything but I'm worried about internally. I dont know what to do. I'm so worried about judgement from every one, even her doctor but I dont think I will feel ok unless I call and tell them what happened.

My SO is upset, rightfully so, and said its my fault, and if I didnt co-sleep with her and put her in her bassinet this wouldn't have happened. I'm so upset, feel so guilty and ashamed.
