I'm glad that it's helpful for you! She really helped me when she told me that. A long time friend of the family said something similar. She just reminds me that I know how the situation is going to end with my grandmother when I set boundaries with her. She's going to be upset. That way I can manage as best I can.

An example of my managing, if I don't set boundaries with my grandmother now, even though I've moved out, she'll probably continue to treat me like her personal secretary if I don't put a stop to it. Since I have a hard time speaking up I'll just not answer her calls. Then I can text her and ask if it's an emergency or what she needed instead of getting bullied into something by talking directly.
