What should I do? Sociopathic Parent?

I am a freshmen in college and it has created real stress with my parents. I work hard, am a fairly good student, I never party or anything. But it had begun to feel like they controlled everything in my life. I am 10 hours away! It started when I would not give my father the password to my student account, which we are not supposed to give out! I signed the form saying he could see my grades but he wanted my account and email as well. I had the housing director call him to explain but that made him flip out even more. The next issue was with my mother. She had always pushed me to Rush for a sorority, but that really did not fit what I wanted out of college and I felt extremely uncomfortable. So I de-pledged. When I told my mother what I had done she became extremely angry. When I tried to explain my reasons she would not let me speak and said things like "what have your father and I done to to create such a monster?" And when I finally was able to say "I've just never pictured myself as a sorority girl" she retorted, "Well I never pictured you with an asian. Hurts doesn't it?" This was in reference to my boyfriend who is from Beijing China. She also said she is sick of hearing about the whole 'international' thing, and to get over it I am not Asian. I am an Asian and Latin American studies major. I have no desire to be Asian, nor do I simulate the culture in any way. I have spent three years studying Chinese. So she wants to hear about a sorority that I have no desire to be in but not my Major, which should be my primary focus? My father was then put on the phone (which was the first time he had talked to me since I would not give him the password) and when I tried to explain to him why I did not want to be in a sorority he said, "Shut up, stop whining, stop complaining. You have been making bad decisions for the past 18 months now and you need to get your life together." He was referring to how long I have been dating my boyfriend. My boyfriend is wonderful and sweet and would never do anything to hurt me and is one of the best things that has ever happened to me. But my parents have stated several times that they would hope that I come back from college with a blonde blue eyed boyfriend. They threatened to pull funding for college unless I rejoined my sorority. So I did. When I texted my mother telling her that I had been initiated she texted back, 'thank you for doing what I asked even though you don't want to, I love you for it.' and then as an afterthought she texted 'oh yea and just for you.' It just baffles my mind that they absolutely do not care that what they are doing upsets me, and even go out of their way to say things specifically to hurt me, with my mother's comment 'hurts doesn't it?' I would NEVER hurt someone on purpose, and if I did say something to hurt someone it would have been entirely accidental. I am currently going to therapy, and she first told me that they were being emotionally and verbally abusive, and showing sociopathic tendencies, and just recently told me that it is her opinion that they are sociopaths. They are coming down for Easter and I have to live with them again this summer. What do I DO? How should I handle this? If anyone else has had a similar experience please give advice.
