Hi
mettagirl and welcome to the board! As
zachira said, many of us can relate to the push and pull of guilt. Having a pwBPD (person with BPD) in your life can be exhausting mentally and emotionally.
Are you familiar with the BPD behaviors that can be so troublesome in a relationship? We have lots of resources I can refer you to if you want to learn about BPD. I don't mention so that you can help your mom, as you really can't, but understanding the behaviors and how most of the time she isn't really seeing you can make a huge difference in terms of taking on guilt and responsibility for helping her. Knowledge helps depersonalize the behavior, sort of external it so that you can work on detaching from the
Emotional Blackmail: Fear, Obligation and Guilt.
How are you with boundaries? Have you tried them?
I din't want to keep hitting you with questions so I am going to stop here. Just know we have lots of articles we can refer you to as you post more of your story.
Again, welcome to the board. This is a great place to share with people who get it and can offer support and understanding as you try to work out a healthier way of interacting with your mother. I can be difficult but it can be done. You don't have to do it alone.
Take care.
