How ironic that your grandmother and mother chose to play favorites and became angry because you tired to express unconditional love!
It is clear that your family, as you said, has the divide and conquer mentality. It seems that you have worked through your own issues to avoid that in your own life. Bravo.
I am sorry that your mother got involved in it at all. From what you said, it was a gift to you, not her, and she needed to stay out of it.
Too late now. What's done is done.
You've gotten some wonderful advice here, not to mention sympathetic shoulders from people who have suffered through the same thing. You're a strong person and you've learned a lot from this. Take care of yourself and heal your heart.
