How can I control my anger?

Hello doctor,

I have some serious problem in my family. I am 20 years old and studying. But something is not going well in my family. I got angry on little things and lost my control over me and behaved like a killer. Also, I have tremors at that time. Always I feel stressed, depressed, and fatigue. For that reason, though I have the eagerness to take food, I take a little.

In my family, my father has some behavioral issues. He is also a psycho patient. All-time he disturbs us behaving rudely and he also got entangled in an outside relationship with a lady and the lady cheated him. So, now father becomes mad. My mother is also a cardiac patient. So, all the time a claustrophobic environment is there in our house. Moreover, the pressure from my father. I am always in fear that what I can do in this situation.

I have another tension regarding my mother. She is always tensed. She does not sleep at night. So, I am tensed there about the current situation. I do not focus my mind into something. I feel that nothing is good around me. Even I dream about lots of bad things. Even midnight I hear that my parents are quarreling falsely. I cannot sleep constantly. Even after a sleep of 4 to 5 hours, I feel like I have done too many hard works.
