When they don't understand why you haven't done something

My mom and her boyfriend have been yelling at me for 3 weeks to clean my room but I physically can't. I've just been trying to stay alive all week and I've been doing alright but everything hurts. And they want me to do the dishes, but if I do that it will sting my wrists, it hurts so bad. And my teacher yells at me for falling asleep in class but I haven't slept at home in over 2 weeks. In the morning all I do is hide in the bathroom at school and if someone tries to talk to me I hyperventilate. My mom told me to punch the people who bully me and to tell the principal that "I'm crazy and these fuckers keep fucking with me" am I crazy. She thinks I'm crazy. I don't wanna be crazy.  Sure I physically can't control my emotions but that doesn't make me crazy dose it. I don't wanna be crazy.
