Hi Ray ! Anger and frustration are the outcome of unmet expectation. You need to change your expectation what you have with your mother. When your expectation will meet the action of your mother you wont feel angry or Unhappy . The reason being you already have expected her to behave in the way she really behaved.

You might have noticed that when you get angry with your mother the impact of the generated bad mood also effects other works you do subsequently. Like if you receive a phone call from your friend immediate after the fight with your mother. There is maximum possibility that you would say bad words to your friends too.
I have recently read a story for similar situation quite related to our everyday life. Check this out. It might be helpful to you too..
