Do you guys feel classic BPD symptoms in all your relationships, or just your closest ones (partner, immediate family, closest friends)? I think my sister may have it, but I'm not sure because she only displays symptoms when she is with a partner. Sometimes also with a very close friend. She easily holds down jobs and has had both of her jobs for several years. I know she would need to see a professional to be sure, but I just want to know is it pretty much a guarantee that if you have BPD it affects all relationships, or can it just affect one or two?
