how could i do self-control well??

You need to stop giving yourself permission to lose control and, instead, give yourself some tools to help you keep in control. Counting to ten before you speak gives you time to calm down. Walking away if possible also helps. Since I am the oldest of four children and I had it drummed in my head from a very young age that I had to set a good example for my siblings I had to learn to remain in control of my emotions and my words/behavior. It's not easy but it can be done.
