It was a challenge with my BPD mother too. She was resistant to therapy or even the consideration that she had BPD. She had also been treated with prescription medicines and was dependent on them-not only physically. At one point, her doctor took her off them. Her anxiety and emotional distress were extreme. She got back on them.
I understand being powerless. It's natural to be concerned for your widowed elderly mother, and yet, not be able to do anything to help the situation. We kids were concerned about my BPD mother after my father passed away. She had been so dependent on him. Suicide threats were a concern too. However, we didn't live with her, we had our own families and jobs. We could not watch her all the time. So we decided if we had any concerns, if she made a threat, we'd call 911 emergency. That's the best anyone can do.
BPD mother also didn't allow us to have any imput or information about her finances or medical records. After Dad passed away, she redid her legal papers, wrote someone else in as POA. We had no idea how she was managing.
What we realized is that- we could not be proactive with her. She was doing well physically. As far as we knew, she had sufficient funds for her needs, but we didn't know any information about that. As long as she was legally competent, we could not do anything, even if we were concerned.
What I noticed with the delusional thinking was that, if there was something going on with her medically- the quality of it would change, but also stress could do that too. It was not possible to tell what was actually going on. There were the usual wild statements- her baseline- like saying a relative was on drugs (she wasn't) and saying someone was being abusive to her when they weren't. These were not without consequences as it did push people away but there's no controlling this. But sometimes she'd act as if she was confused, didn't know where she was, thinking she was somewhere else- and these times were when it was medicine or an infection, or dehydration.
Still, there was no way to control this, or intervene proactively. It could only be done in a crisis situation. It's also difficult for you due to expectations. People wonder why an elderly person is "left" to fend for themselves - where are the adult children. Also for the adult children who are concerned but have no ability to intervene, as well as who also need boundaries on abusive behavior.
Around this time, I also saw what "normal" is. My inlaws were getting older. They sat down with their adult kids, gave them all the information needed, expressed their wishes, made them POA. They had their moments too-of frustration, anger, the "normal" for this situation. With BPD- there may be similar circumstances but with BPD influencing the behavior.
This is an emotional situation. It's important for you to take care of your own emotional well being. Prepare yourself for what to do if needed. I did consult an elder law attorney and social services to learn the rules, and resources. It helped to know what they were, even if I couldn't do anything.
How much we could be involved was determined by BPD mother. At one point, she rewrote her legal papers, made her kids POA. But even with the POA, BPD mother remained self directed, and made her own decisions.
If your mother won't establish someone as POA, there may be a point where someone has to legally step in. It can be you, or someone else. Being POA is voluntary.
Without any ability to be proactive, have a cooperative relationship, all we could do was keep a watch on her, determine what we were willing to do if needed and if she allowed us to.
