Not liking my mother Part 2

I really struggle with my thoughts and feeling towards my mother.
There are parts of my mother that I don’t like.
I don’t like the way she talks to other people.
I don’t like when she yells.
I don’t like when she speaks down on other people.
I don’t like when she always thinks she right.
I don’t like that she has trouble seeing other people’s point of view.
I have a lot of anger towards my mother for the way she treated me growing up and I don’t want to let go of that, I’m not sure why that is so.
I think that if I let go of my anger towards my mother that it would be mean that I agree with her behavior.
Do you have any insights for me?
