I was like this and had a note on my phone I made myself read when I felt myself getting angry. Just things to bring me out of it.
I just found it on my phone - I realise not everyone will agree with all of this but this was my way of snapping myself out of it:
Anger is normal and we are responsible for what we choose to do with it.
I am capable of 1000 times more harm in one action than anything that is thrown at me
Violence sabotages and undoes all the good - it is not ok to discharge in this way
Your child is not the cause and is not your enemy
There is nothing constructive about expressing our anger to another person - it is not true that unless we express it, it will eat away at us
Once calm look at what made us furious. What is wrong in my life that made me feel so furious?
What do we need to do to change that situation
We will not find the answers to these questions by acting in anger
Offer a role model and don't hurt
Screaming is a tantrum
Might does not make right
Show how anger is human and handle it in a mature way
'I am too mad right now to talk about this. I am going to take a timeout and calm down'
Model self control
This is not love withdrawal
Go away to calm down then go back.
'This is not an emergency... Kids need love most when they don't seem to deserve it...she's acting out because she needs help with her feelings...this too shall pass'
Do not ruin your child's life as the effects are lasting
Planning:
Set limits so everyone knows what is expected
Stop
Breathe - elephant 3 times
'This isn't an emergency'
Shake the anger out of my hands
Noise - hum
Smile
What is under the anger?
Fear
Sadness
Disappointment
It is ok to let these in and feel them
NEVER act while angry
Ok to say 'I need to think about what has happened and we will talk about it later'
Don't repress the pain of my own childhood
Mindfulness practice - 20 minutes a day to strengthen brain's response to anger and make it easier to calm
