Welcome to the parent's forum, Chittychitty. I am sorry for what brings you here, but am glad you have found us and I want you to know that you are not alone! I felt compelled to respond to you as I could have wrote your post pretty much word for word about a year ago. I have a BPD dd21 who is stable and doing well at the moment after years of behaviours similar to what you described.
The crazy making part of this is that she swings back to being a loving and appreciative daughter. This vicious character assassination usually occurs in private. So when I try to explain it to others I feel I look either nasty or mad.
Chittychitty, I totally know where you are coming from with the above quote. I remember feeling so relieved when my daughter finally could not keep up the constant façade with other family members (most especially my mother, who loves to play devil's advocate with me). It was such a relief to be able to say... ."see, Mom, I'm not exaggerating... .this is what we have been living with for years!"
Chittychitty, please know that you have no need to explain yourself here, no need to justify. We GET IT... .we have all been down a similar dark path... .We accept each other at face value on this forum, do not judge and I guarantee you will finally feel understood and supported. Please keep posting and share more details as you feel comfortable... .
Whatever I do or say infuriates her. For now I have not responded as I simply do not know what to say. I cannot agree with what she says, but if I contradict her it causes more distress and rage, so for now I have not said anything which I am guessing will also be misinterpreted.
There are a ton of excellent learning resources to help us better communicate with our BPD family members. The lessons on the right hand side of the page under the title "Family Connections" are a great place to start
When I joined this forum a little less than a year ago, my daughter and I were scarcely able to have a conversation without is spiralling into something volatile. I had almost given up hope... .and then I found this forum. The immediate validation was incredible, and then when I started implementing some of the things I learned here, a light started to appear in the dark tunnel that had become our existence. The key is changing your own reactions and behaviour. Even if it doesn't change how your daughter responds to you (though it likely will, at least somewhat), you will feel better within yourself... .More in control... No longer the victim... It is so important to escape from that "victim" mindset. It was Huat from this forum who told me not to be a victim, and while it took me a while to understand what she meant and to stop playing that role, it was bang on. When you take back your control, you do things by choice, not by manipulation and guilt.
You are very obviously a loving, thoughtful mother, Chittychitty, and your daughter is very fortunate to have you in her corner. Peruse this site and post freely... .You are amongst the very best of people here... .We understand each other and we want to help.
