Hi Joan7

You have been dealing with quite a difficult situation for many years now. Living with a BPD sibling can really take it's toll on you so I understand your anxiety. Many of our members have been traumatized by what they experienced during their childhood. I am glad you had a therapist though to help you with these things. Are you currently still seeing a therapist?
My parents were not abusive, but many of her classmates at school were. I got bullied at school too, and pretty badly, but I never turned out like my sister.
I am sorry the two of you got bullied. I got bullied too in high school and know how hard this can be, especially when you are also dealing with a BPD environment at home.
Even early this morning I received 11 very angry text messages at 7:30am: they detailed why any of my character traits, accomplishments, and college education are worthless next to hers and why I was a horrible human being; really brought me back to my childhood. Why text me these things? She was angry I told my mother that she tried to buy my pain medication off me. It was for my recovery from wisdom teeth removal; she does not need them and her reliance on prescription medication worries my mother. She already takes Ambien and Klonapin, and often has lied about the dosages she's received. (She also has never finished college and can't hold a job.)
It sounds like your sister is engaging in the BPD behaviors 'projection' and 'splitting' here, are you familiar with these BPD behaviors? You can read more here:
BPD BEHAVIORS: Projection BPD BEHAVIORS: SplittingI am beginning to understand that what I have experienced was traumatizing, and acknowledging that is okay. I know that my sister suffers greatly, and that my mother and father have much more to deal with than I have, but that doesn't invalidate how I feel. I am still very angry. I have more maturity than I used to and can deal with the situation better, but when my sister says she needs to "talk" to me about something my heart rate still rises exponentially. Once I left for college I began to see a therapist, who verified that my sister was someone I should avoid for the sake of my emotional health. I used to think that I should go home to support my parents - to "do my duty," so to speak, but then began to have panic attacks whenever I got home. On several occasions during a winter break, I would wander around outside late at night simply to avoid her. Then I stopped going home during college, which agreed with what my therapist thought was right for me.
Why do you feel your mother and father have much more to deal with? Is it because you have been away to college these last couple of years?
You grew up in this difficult environment which really isn't easy. Your parents are adults, but you were just a little child faced with a disordered older sister.
There is nothing my mother, father or I can do to help my sister. She has to help herself, but she doesn't want to. She still claims that we are the delusional ones and that there is nothing wrong with her.
Your sister had been officially diagnosed with BPD and OCD and has also been hospitalized several times. Has she ever gotten any targeted treatment for her BPD?
It is very unfortunate that she doesn't acknowledge the problems she has. Do you feel that your parents do fully acknowledge your sister's issues? How is the relationship between your parents and your sister?
I am glad you reached out for support here
