Hi BPDMom29,
Welcome to the Parents Board, we are happy you found us and sorry to learn that your daughter has BPD.
How old is your daughter and do you know what kind of therapy she is attending?
Isolation can be a big problem as it is a sign of depression.  :)oes your d take any meds for depression? Sometimes social anxiety contributes to isolation as well.
Have you talked with your d about what feelings she has regarding friendships? Maybe she feels judged by others, disappointed by friends in the past, abandoned by them... .? Validating her feelings and then asking her validating questions to gently guide her towards accepting others may help. Encouraging her to pursue interests like art, music, volunteering at something she likes can be a good first step.
The black and white thinking about relationships/friendships can feel like there is no point in having friends to a person with BPD (pwBPD). Our kids can be so easily disappointed when friends don't live up to their expectations. Here is some info on black and white thinking, also referred to as Splitting, that can better explain how their thought processes work:
