He who can't control his anger

Right now, I'm very sad very angry with my dad and myself. I don't understand how can he scold my mom in public. Since I was a kid he was like that. He has very bad attitude when he got angry. He was a ex counselor, he give advice to people, how can he can't control his anger. He always angry with my mom. I'm very sad because I couldn't do anything. I feel bad. I don't know how she can live with him for years. When we are in trouble, or even we don't do anything wrong, he got angry with mom like crazy. I'm very sad and angry with myself because I talk bad about him, like right now. Mom I'm very sad, you must feel very sad than me. I hate him when he got angry, very hate! I won't let him sent me back to hostel anymore, I won't ask him to go out or even back home. He will get angry everytime. I'm very tired because I'm too sad and angry. I want to sleep. Something like this can make me having really bad mood. I'm tired dad, why can't you change 😢😢😢
