I don't think it's abusive, BUT I'm not a social worker. Discuss this with your school nurse. She is a mandated reporter, IS REQUIRED TO REPORT ABUSIVE BEHAVIOR.
If Child Protective Services believes you are being abused you will be removed from the home and placed in a foster home unless/until a relative takes custody of you. At age 18 you will be released from the custody of CPS.
If your mental health is being harmed, yes, report her obsessive behavior. I doubt you'll enjoy foster care, and you won't have a phone for anyone to track, but no one will be spying on you.
