I'm going to tell my mom I have cut myself over a stupid argument about food with her.
Why did your mother drive you to cut yourself over a food argument?
She's very stupid and I don't respect her at all.
I know that you don't feel as though your mother was respecting you in your discussion over food, but that is no reason to further the argument any further. Don't argue with your family, find a way to communicate your feelings to them.
Fuck my mom.
Don't say that. Be mature and talk to your mom about your issues with her.
