Misunderstood

My grandma is complaining about everything. I think she's just looking for an excuse to be mad at my mom. She's told me that I can tell my mother 'go to hell'. She went on a rant about how she wouldn't leave my mom any money even if she had a million dollars. And she said she didn't care about her or the wedding. What sparked this rage? She thought my mom blocked her from emailing her. I just went through it all with her and showed her that the little 'x' by my mom's name in the email address is giving my grandma the option to block my mom, not telling her that my mom blocked her.
