I feel really bad about it. I'm still crying.
I don't know what happened, she was having a tantrum and slapping me and I don't even know how I did it, but next thing I know I'd slapped her. It's like I didn't have control of my body for a few seconds.

I feel really bad about it. She's a good kid generally. She's teething so I've had no sleep, but I know that's not an excuse. I just don't know what happened?
