I want to remove my mother from my life. I just don't want to see her anymore.
Why do you want your mother out of your life?
Her constantly giving me suggestions and instructions irritates me.
Have you tried talking to her about how her behavior makes you feel first? Having your parents in your life is a good thing, but if they are causing you more mental harm than good, sometimes you need to detach yourself.
I can't keep listening to her trying to control me. Besides, my life will be better without her.
You should maybe just give yourself a little space and get some distance. Removing her from your life completely is going to cause a lot of pain in the future. You will really miss your mom when you can't talk to her.
