I'm going to tell my mom she has to shower? She only showers once a month and she smells like a homeless person
Why haven't you told her this before?
I'm afraid of her. She yells at me and she hurts me physically.
People are expected to have good hygiene. You should seek out a friend or family member who you can talk to about your mother's abuse.
Okay I will try that because she smells really really really bad.
Hygiene is important not only for the individual but everyone else around them. The smell can't be compared to anything else, I agree. Please make it known to others and get them to help you with her.
