Is It Emotional Abuse?

A teenager gets into frequent arguments with her father, which almost always end in both yelling and the teenager crying. The teenager is afraid to talk to her father or even be in the same room with him. She considers her bedroom as her safe place when she is upset. During their worst argument, she retreated to this safe place. She closed the door and sat with her back against it, trying to hold it closed. The father forced the door open. She ran to her bed, and he continued to yell, telling her that she deserves to be ed. Arguments usually begin over perceived 'attitude issue' such as irritation and frustration audible in the teenager's tone and response to questions, or unwillingness to have a conversation with the father. After learning a few basic body language signals, the teenager realized that her body language most often read as 'defensive'. She does not often feel emotions, often 'faking' happiness and enthusiasm when she believes these emotions to be appropriate responses to her environment. Therefore she is perceived as being a generally happy person. Many people she knows have never seen her really upset or angry. She is easily irritated by her younger brother, sometimes getting frustrated and even yelling at him. She rarely feels lonely, often choosing to be alone whenever she is at home, rather than spending time with her family. In recent months she has recognized certain signs such as low self-esteem, difficulty accepting compliments, surprise when someone does something courteous such as holding a door open for her or handing her something she dropped. She has difficulty being decisive and ertive, often unable to take a leadership position in group situations. She often has difficulty asking for help. When she has difficulty accessing her locker at school because someone is blocking it, she is often unable to ask them to move, but rather waits for them to move on their own, sometimes risking running late for cl. She has trouble interacting with men, especially those close to her age. Is she being emotionally abused? If so, what would be the most effective option for this teenager?
