I read your story from the perspective of a grandmother whose grandchildren have severed ties with her. At least one grandchild has what I'm sure is undiagnosed BPD; the other is just an opportunist and has no use for me unless I pay him money. I have made it know that I continue to love them and am willing to be there for them. So my situation is quite different from yours, though we both feel pain. I found your story compelling, because it helped me to understand BPD. I wish you well. I send you love form an unknown and unknowable source.
