Dear bwale:
Your father is wrong for screaming at you. You probably cry because he screams at you. It is very difficult to be screamed at by someone you loved your whole life, your father. Unfortunately, if he never apologizes to you for screaming at you then he probably has no intention to change. It is not good for you to live with a person who screams at you and bullies you (and another person in the home, your mother). I think it is a good idea for you to find a way to move out of that home, away from your father.
Wherever you live, number one priority: let there be no person in your home who screams at you, who mistreats you in any way. Your home must be a safe place where you are either alone and safe or living with others who respect you, others who keep their voices calm and down, people you can trust to be calm, that is where safety is.
