Mom's/Dad's did you ever say something to your child that you regret?

I have three kids 8 year old, 5 year old and 9 month old. This morning my 5 year old daughter gave me such a hard time as with every single morning. She had to wear a certain dress, I told her it would be chilly outside and she insisted on wearing it so I gave in. When we are all three walking out the door she decided she didn't want to wear it anymore and started crying to change, I loaded my boys up in the car, went back in the house to change her and nothing I picked was good enough, out of frustration, I said " Ohhhhhhh I can't stand you sometimes" I feel like a horrible mom.
