I was wondering reading your first posts if perhaps you come from an Asian family, because that is the only way what you were posting makes sense. My daughter has several Asian girls that she is close with who have to face exactly what you are going through. I think that what you are experiencing has really less to do with who you are and who your parents are as people and more to do with you being culturally very different from your parents.
My daugther’s friends have parents who think that their daughter must attend the colleges that they choose for them, major in what what the parents want, and have careers selected for them by their parents. To not give them total obedience in this causes a huge, huge conflict. One of her friends, who is a very good girl but has been virtually kept under lock and key because her parents don’t trust her recently went and took every medication in the medicine cabinet and came so close to death. Even a week after she got out of the hospital she was swollen and had difficulty walking. Did her parents realize how wrong that they had been? Did they understand how bad they were making her feel? No, while she was still in that state, they drug her off to parties, where they told everyone what a horrible daughter she was.
I really hope that your parents are not that bad. I think the only way that you have to handle this is to be respectful to the degree that your conscience guides you and to not become emotionally involved in their game. Just do what you know is right, keep on being loving, and kind to your parents, but firm in regards to your own personal goals. Eventually they may come around, but don’t be too disappointed if they don’t.
I guess the reason that I am posting all of this is to let you know that you are not alone, that your parents are not treating you this way because you are a bad person. Just hoping that deep down you really do realize this.
