Dear you, Sometimes the biggest challenges in life have just one solution. A old school promise to self. Which is yours and no one has any right on it. Sit alone and think and feel everytime you have been provoked by life and everytime you have regretted getting angry. Did you feel good or happy ?? You already said the answer. Make a promise to yourself and don't tell it to anybody . The promise is like loving yourself. Promise could be "No matter what happens I will not hit myself and my parents" When you will remember this promise and you will be able control your hands even once. The change will happen. A promise is a start to self love.
