I haven't spoken to my mother on the phone for months and I don't care
Why don't you talk to your mother anymore?
I don't want her in my life anymore.
Relationships with your parents can be difficult but it is not good to just cut them out of your life. You might regret it later on.
Nah, I am trying to be independent and live on my own.
Have you explained to her what your problems are with her? It can be hard to not have a mother's love in your life, and telling her your feeling may cause her to change.
