Why is my father so ughh?

i hate him so much i can't even stand it. He has such a hard time trusting others. He doesn't even trust me and my family. somehow he always thinks negatively, he thinks everyone hates him and wants him to die. i remember him once saying," you want me to die don't you?'' today a lady from the U.S census came door to door to my house asking about victim of criminals. in the end we gave them no information except for our names. then when she left, he started to yell at me and my mom. saying did you know in LA there was a family that had a fraud when someone came door to door to their house. watch, they are going to take all our money. what if they want my head? who from the government works at this hour? blah blah blah. he always take small problems and turn it into bigger problems. sometimes it doesn't even make sense. then he asks me why do you trust people so much. wheres the proof that she was a U.S census. I answered "well she showed her I.D." so what that proves nothing. he said. when i argued back he raised his voice and wanted to hit me. he said who the hell you think you're talking to? sometimes i wish i didn't even have a father. i always have a feeling my life would be wayyyy better with out him.
