Welcome Jobby2015: Sorry to hear about your mom. I've read the, "Stop Walking on Eggshells" book as well. It helped me understand what was going on with my sister. Has your mom given you "the silent treatment" before? Is your father in the picture?
Are you able to share some of the details that led up to the current silence?
We can't change them. You can, however, make some changes in the way you interact with your mother and how you react to her. By using some communication skills and boundaries, you can make thing better for you.
