My questions to the community:
- How do you handle conversations that always spiral, even with a therapist present?
I don't have spiraling conversations. If I see it's going that route, I'll tell my BPD that I love her and I'm stepping away before either of us gets angry. Not that I'm getting angry, but it's easier to say "we" than "you" to someone unstable. Then I step away for a bit and pick up the conversation when things are calmer.- How do you handle conversations that always spiral, even with a therapist present?
- How do you keep your sense of self when every argument makes you doubt yourself?
Your sister is mentally ill. You claim that you're not and I believe you. That means when things start to go sideways, it's up to the sane person in the room to not "take the bait" and get into an argument. If my BPD wants to argue, I literally just walk away...and I'll try to tell them that I love them and I don't want to argue.
But if that doesn't work, then I just walk away (or hang up the phone, whatever).
- How do you set boundaries without becoming “the villain” in the other person’s narrative?
Boundaries are for you and only you can enforce boundaries. It doesn't matter what anyone else thinks or how they react to your boundaries; it's up to you each time to use them in a predictable way.
For instance, if I tell you that I won't speak to you if you say the word 'banana,' yet you say it to me three times fast mocking me. I can't stop you and I shouldn't argue over what you decide to do- that's not the boundary part. Instead, the boundary determines what I'll do if you don't respect what I'm asking you to do...so I walk away.
Now, if you make a boundary with your sister that you won't talk to her if she's arguing, then she's probably argue even more. That brings us to the previous questions you asked, you simply stick to your boundaries and exit the conversation. You can do that in a loving way though and it makes you very predictable- if she yells, you're retreating.
The way I explain it to my BPD is that my boundaries are for me, and she can decide to respect them or not. I make it very well known though:
- If you yell at me, I'm leaving so everyone can calm down.
- If you hit me (or anyone else) I'm dialing 9-1-1.
- If you leave my house a mess, you're not welcome to stay here.
Here's the thing though; your sister is making all the decisions. If she's nice, you talk things out. If she's mean, you leave. If she's violent, you call the cops. Every action you take follows a very obvious set of rules that she knows about. So it's not you doing this or that, it's her deciding what you'll do next.
Every decision is ultimately hers; you're giving her all the power and just reacting accordingly.



all I can say, BPD is a BEAST; please free to reach out, if you like....I wish you good luck and am sincerely sorry you (and any in this group) are going through this
