Hi, seekinghope And welcome... . You really
are in the right place for the help and solace and information you are looking for

I am so sorry for what you've been dealing with for 45 years, but so glad you are here
Everyone here knows the pain and heartache inherent in any relationship with a person suffering with BPD, and many are here because of their relationship with a BPD Mother. Has your Mom been diagnosed? Has she ever been treated for it? Have you, yourself, ever seen a Therapist to work with what you have been dealing with?
There are many
Workshops,
Articles and
Videos here that will help you here, but below is just a little start:
How a Mother with Borderline Personality Disorder Affects Her ChildrenTo find others who are posting here because of their family members with BPD (and
especially Mothers; there are lots of people here because of their Moms!), this is the Message Board where you will find many senior members with experienced advice and sympathetic ears:
[L5] Coping and Healing from a BPD Parent, Sibling, or Inlaw BoardI know what a BPD Mom is like... . Not my own Mom, but my Husband's; and I've been dealing with her as a DIL for 39 years! I can so sympathize with what you are feeling; I've listened to my Husband's stories of growing up with her, and seen with my own eyes and heard with my own ears the rages and abuse that she generates :'( Though I know that I'm able to detach from her venom a bit easier than her own children can, I do see and feel what my H and his siblings deal with.
Actually, I do believe that you probably have it
much worse that they do; at least they have each other to talk to and commiserate with and blow off steam with. I am so sorry that you have to deal with all of that all by yourself I bet you will find someone who is in just your situation over at the [L5] Healing Board mentioned above... . Please read and post over there when you feel comfortable; the support you will get will at least shine a little light for you to follow and embrace... .
I'm so happy that you have a supportive husband, and I wish you all the best with your son. Do you live close to your Mom? Do you see her often? Glad you are with us
