Big hugs. You have so much on your plate with four kids, selling your home, no me time etc. Its no wonder your stressed and totally lost it. Nobody is perfect and sometimes one little thing can set you off.

If ever I get to the point where I feel out of control with my kids I take a deep breath, count to ten and go outside into the backyard. If I still am reeling I go to a spot where the kids cant see me and throw a brick as hard as I can against the grass (multiple times if necessary), this really helps me get the anger out. Then when I have calmed down I go inside and face the situation with a level head. Perhaps its a strategy that might help?

I hope today is a better day for you.
