No matter their diagnosis, the most important thing for you is boundaries. You were right to not play into her drama at the mall. My bipolar/addict mom did that to me once at the mall--she actually got out of the car in the middle of a busy street, and walked to the mall. At the time, I was still very involved in her drama. I called my grandfather to help me find her in the mall. What a mess. I was so upset--crying, etc., and she was enjoying her manipulations. The rollercoaster ride stops once you get off of it. It took me a long time to detach from my mom. I can't always do it, but now I pretty much won't allow her to manipulate me to be involved in her drama. Although, I don't know if I could manage it if we were living under the same roof.
