Angry mom

I hope that I'm not the only mom who struggles (almost on a daily basis) with anger, impatience, discouragement and a whole list of other emotions.  Most of these, Satan uses against me.  It's not a sin to be angry (Matthew 21, Mark 11, and John 2 tell about Jesus' anger with the money changers in the temple)  His sin was justified.  His anger was not selfish.  His anger was not about someone, but about actions and the sinful behavior taking place in the temple.
In Ephesians 4:26 God says "In your anger do not sin."  It doesn't say "don't be angry."  But honestly, in my life, anger is a sin.  My anger is mostly directed at someone and normally because something isn't being done the way I think it should be done.  The kids are arguing, toys aren't put away, it's too loud, the laundry NEVER ends (dishes too) my list can go on and on...
Really though, my anger leads to sin.  I scream and yell (A LOT) and most of the punishment is done in anger.
So, today, in an effort to control the way my emotions get out of control and lead to sin, I have taken a "vow of silence".  I will not be speaking today.  God has lead this decision.  It isn't something that I am doing because I'm tired of hearing myself repeat everything.  I've explained this to my kids and they understand (well, the older two do).
My first reflex to yell - it won't happen.  I have to stop myself and think about a different way to respond.  My prayer in all this is that God will reveal himself to me and show me how to ward off evil.  James 1:19-20 "Everyone should be quick to listen, slow to speak and slow to become angry, for man's (or mom's :)  ) anger does not bring about the righteous life that God desires."
I want, no, I desire that my kids see Christ's love through me.  I want them to see it, experience it and in turn, spread it.
On a side note, this may help with our sign language.
