I grew up with a father that was very controlling and I was afraid to stand up to him, and therefore learned to be afraid to stand up to anybody. Now I am 29 years old, and I still let people walk all over me. I do whatever anybody wants me to do, and when someone does something I don't like or treats me badly, I always just keep quiet and don't say anything. I know one reason I do this is because now that I am away from my father and don't have to listen to the yelling all the time, I want to do everything I can to avoid arguments and yelling. As a result though, I am pretty unhappy but nobody knows it. Any advice on how I can get over my problems from growing up, and start standing up to people?
