Welcome.
I have broken into tears countless times since she has been here just this week, I feel like she causes me so much anxiety.
I appreciate what this may feel like. It's frustrating to have an environment where you are stuck with a BP. Not knowing what are effective and ineffective things to do, that would make me feel anxious and uncertain—anyone would feel that way. So of course you're not alone in this. Lots of us here have dealt/managed/are-managing people with BPD (or fit the mould).
I read a lot of anxiety and uncertainty in your post. Having survived a short horror-movie of a relationship with someone that fit the profile, I know a bit of what it may feel like for you.
A few suggestions from me.
I highly recommend you get a therapist (T) to support you. It's incredibly taxing for the person in the relationship (any defined relationship type) with the BP (these people are called the "non"s) to handle the BP—let alone improve a situation. Hence I highly recommend you get one. That's consistent with the board's recommendation too.
Spend time privately researching for someone qualified. Try them out. What was effective for me—I found it was much easier for me when I didn't tell anyone about this. I only shared it with the board, and someone I trusted but not related to my family-of-origin (FOO). Things blow up with some people (esp. BP's) when they find out that the non is getting help.
I just don't know how to proceed with her.
First thing I'd go to is learn basic "
SET". It's one of the quickest and most effective ways to manage any situation BP.
Few tips for after you practice alone or with a friend (I've done this):
- Get all the elements out in order.
- Keeping quiet and coming back to SET is better than following your impulses to say something else or retaliate.
- Know clearly what you want in that 1 minute, then segue the SET into what you want. E.g., to exit the situation to "do something else", take the lead on it.
Third recommendation is self-care. Definitely do those and learn to do those. Things like massages, mani/pedi (if you're into that), walks in places you enjoy, enjoying great food, prayer. Self-support.
Any help or similar experiences you could provide would mean so much to me.
I'm hoping others will add to the discussion.
When things have settled down for you, please do have a look at the
lessons. They'll be helpful for the long run.
I wish you peace and hope you'll share more.
