I am not my mother.
I do not reject my mother. I reject her behavior. This is healthy, safe, normal, fair, justified, and right.
I will not be guilt tripped or goaded into a response. I will not respond to petty threats. I will not let these things weigh me down.
I finally got fed up enough with her today that I blocked her. I don't deserve to deal with that in my life and that's that.
