Talk to a school counselor. This is physical and verbal abuse...very dangerous; she could put you in the hospital or kill you. Whether you push her buttons or not is irrelevant; she CHOOSES her behavior (if she really does black out and doesn't remember); this is all the more dangerous; keep speaking up until someone helps you. This won't stop until yu find a way to stop it.

Yes, your mom is wrong.....abusive. Ihad a mother like that and understand.

She abuses you because she can get away with it (most abuse is done behind closed doors); if she abused anyone else, she would be arrested. Abuse is a CHOICE. Is there anyone you could stay with for awhile?
