Hi Hopeful4Future
So sorry you’ve had to deal with all this. Been through similar and it’s tough. But help is at hand on this website, so your comment:
“When I try to talk to people in my life about it... .I’m not sure that they believe me. Or maybe it’s too much to respond to.”
I found it to be they don’t know how to respond or relate, but you will be believed here (we share the same experiences) and people know how to respond. So of course she would make you believe it’s your fault for the physical abuse. I had 7 black eyes in a year due to being “clumsy” (not). I was also told I was unwanted as a child etc...
What helped me, was to realise that a BPD of the age your mother must be, is unlikely to ever change. So unfortunately that means she will try and sabotage your wedding (as she did with your brother and as mine did with mine an my sisters). But you always have the choice to decided how you handle it. My sister barred my mother from her wedding and I allowed her to do her crazy rubbish.
But here you will get validation, we will listen, we want to (it’s therapeutic to help others) and you get great advice, especially from the forum moderators. What helped me recently has been watching “Everyone loves Raymond” sit com about his real life mother who has BPD and father NPD. The following clip is about how his mother wrecked his brother’s wedding, he reveals how he copes with his mother. Bear in mind that most of his joke refer back to all the criticisms made by his BPD during the wedding she’s just wrecked:
https://www.youtube.com/watch?v=oVPcklJ8M0wI wouldn’t recommend confronting a BPD in this way (my BPD would hit the roof), but boy is it funny to watch from a safe distance. My friends and I use to joke about my BPD (never to her face). I would recommended taking advice from the moderators on this board for more conventional techniques to cope, and are many for you to try. Welcome.
