Hi and welcome to the board. I am sorry for the situation that brought you here and especially sorry about the passing of your father but glad you found us. We can all relate to having a family member with BPD or BPD traits so you are in the right place for support, understanding and even advice regarding what has helped us in similar situations.
Can you think of what may have caused your mom to flip out or is it possibly related to the stress of your fathers passing along with losing her home? I am not looking to excuse her behavior, rather to understand it. Sometimes being able to link this sort of behavior to a reason can help us understand and process the events.
Being sworn at and told you are evil is quite painful and I am sorry for that. Sometimes pwBPD (people with BPD) will experience difficult emotions they have no way or processing and instead of trying to manage them, they project them onto those who are closest to them. Are you familiar with
Projection?
Projection is a defense mechanism, operating unconsciously, in which what is emotionally unacceptable in the self is unconsciously rejected and attributed (projected) to others. Projection is denying one's own unpleasant traits, behaviors, or feelings by attributing them, often in an accusing way, to someone else. Projection can be quite confusing and painful to be on the receiving end of it.
Recognizing what may be happening with your mother again is not to excuse her behavior but it makes it easier to distance yourself emotionally so you are in a better place to act in ways that are healthy for you. How are you at setting boundaries with your mother? Having strong boundaries is vital to having a working or workable relationship with a pwBPD.
As you share more of your story we will be better able to guide and support you. I hope to hear more from you soon.
