Welcome back dust09: I'm so sorry about the situation with your family and all that you have been through. I'm wondering if the caretaker role you assumed for you sister might have something to do with some of your relationship problems. Have you discussed your sister with your therapist?
You can't change your sister, but you can change the way you interact and react.
I feel bad because I'm her older sister. I should be there for her but every time we are together she puts me down and if I bring someone with me so she won't call me names they just end up telling me how pretty she is. It makes me want to die. I don't know if she is borderline or it only comes out around me because it reminds her somehow this is how I am to be treated since my father also picked me out of the bunch to abuse. I know she will be hurt if I don't see her but I haven't been able to function right for months anticipating this trip. I'm sorry this is so long but I need advice desperately. If I felt good about myself and my life maybe I could handle it but I can't
Your sister needs to understand that it's not okay to be cruel to you. Maybe you could draft a letter to your sister. You could perhaps, gain the input of your therapist.
My therapist suggested that I use "I" Statements with my sister. Examples would be:
Situation 1: Name Calling
Feeling: I feel angry and frustrated
When You or When: When you call be an "F" ing B_tch.
Because: I don't want to be around someone who calls me names. It only causes harm and doesn't resove anything.
Statement: I feel angry and frustrated when you call me a name, because it only causes harm and doesn't resolve anything.
Situation 2: Rushing towards me during a fit of rage
Feeling: Threatened
When You or When: When you are angry and get too physically close
Because: It appears as if I'm about to be hit.
Statement: I feel threatened when you are angry and get too physically close, as it appears as if I'm about to be hit.
