Hello BodieMarie,
I would like to welcome you here

You have come to the right place for help and support, it can be so challenging when dealing with someone with BPD, and sometimes more so when that person is a son or daughter.
I just want her to get the help she needs.
I can relate to that, as I’m sure many here will also be able to. Does she recognise that she has a problem and that she needs help?
Currently I am her enemy and the one she blames for all of her struggles. Yes, she has created this isolation. She has me blocked.
I understand how this must make you feel, my son blames us for all his problems and says that he was abused as a child, his reality and his truth are different to ours and our other children. I am sorry to hear that she has blocked you, although I’ve not been blocked by my son he is NC (no contact) with me and has been for over a year now.
Setting boundaries and trying to follow thru! This has been a total struggle for all of my family. Family outings? As long as she’s not invited.
I believe you when you say that setting boundaries and trying to follow through has been a struggle. There is an article to the right

Under the TOOLS heading, see Communicate Boundaries & Limits. It might help you with setting boundaries, bearing in mind that boundaries are there for you, for your own protection.
I understand that family outings can be hard too, you need to consider other family members, what a shame that your daughter cannot be invited along. I do get it x
