Hi,

I have been searching the Internet for help with my relationship with my sister. I am sure she suffers from some sort of personality disorder or something and I just don’t know what to do.

It is a long story but her behavior can be angry, cold, controlling, hurtful and then she can be nice and sweet which makes me feel guilty for being mad with her and I then suffer by questioning myself. I feel really depressed at the moment and have tried to talk to her, asking her to open up but she won’t talk about anything and prefers to just 'get over it' - shutting me out again makes me feel worse, my mind goes into over drive and I’m making myself ill with worry.

I can be more specific with examples of behaviour, but firstly is there anyone who can offer their support?

Thanks

Having worked with various kinds of mental illness, I can tell you that personality disorders are emong the hardest to deal with as there really is no medication or therapy that will "cure" it. You may have to accept that your sister is the way she is. It may become necessary for you to keep a healthy distance from her. I dont mean that you should stay away from her, but that you can keep in mind her problems when you are interacting with her. A very typical behavior is that of manipulation. If you are aware that she is trying to manipulate you emotionally or otherwise, then you can take away her ability to do it.
Good Luck.
