Hi BPDfrere77,
Welcome to bpdfamily, the circumstances that have brought you here aren't very pleasant though.
Your profile says the person in your live is a sibling and based on your post I assume it is your brother, is that correct?
I am sorry to hear your family-member is exhibiting this troubling behavior. It definitely isn't easy seeing a loved one struggle like this.
If you haven't tried it already, you could use the Psychology Today site to search for therapists and support groups:

We cannot change our BPD family-members, but what we can do is change the way we respond to and interact with them. There are several tools that can be very helpful such as
S.E.T. and
D.E.A.R.M.A.N., are you familiar with these techniques?
