Hi Xorp Sixela
I am sorry your mother's behavior has affected you so. It can indeed be very difficult dealing with the stress often involved when having a BPD family-member. I am glad you doe have support from your grandmother and husband. Are you talking about your maternal gradnmother and how does she view your mother's behavior? Does she also think your mother has BPD?
I want her out of my life forever but she is my mom... .i should try to make something work right?
How you decide to move forward this relationship is totally up to you. I think the most important things is having firm boundaries with your mother and being willing and able to defende/enforce those boundaries when necessary.
You mention PTSD in your post. Many of our members have struggled with (c)PTSD. We have a thread here that I encourage you to take a look at:
