I found people usually treat others like they have been treated. I suspect your mom is unaware of how what she says effects you. If you’re up for it, why not shock the hell out of her by telling her you know what she’s saying, you understand, and you know she loves you and you love her too.
Sometimes we just have to take the high road and rise above it all for the sake of some peace.
If you find that too much to ask then simply let it go in one ear and out the other.
I grew up with a very verbally abusive mom.
