Worst mother ever..

Im having a hard time keeping my cool.

Ive had no sleep for weeks because the kids and husband thought it would be cool to all get sick at the same time. The kids have been out of school for a week. Justin has been here since Tuesday. Alls these kids do is argue. And constantly complain and ask for there stupid ipad. Yesterday during the babies nap time i sent them downstairs and asked for quiet. Instead they woke her up. I was mad. Yesterday after the water park chase randomly started peeling paint off the wall, so i sent him to timeout for ten minutes. Then in the evening we went to pick up Hubby from work and he's peeling off the weather strip off the sunroof of my brand new car mind you... So he was grounded off the iPad for yesterday. I feel like I'm constantly losing my cool or yelling. Am I the only one?
