I'm going to yell at my mother
Why do you feel the need to yell at your mom?
Yelling at her is the only way to protect myself from her anger.
Yelling at a parent is inappropriate. You should respect your elders and be nice to them.
What? I can't take any of your BS seriously.
If you yell at her she might take away your phone as a punishment. If she is really angry you could talk to someone at school and they are better suited to get you help for your situation.
