Here's what you do:   NEVER speak to the principle without a parent/guardian ever again. If the principle tries to speak with you alone, tell her that because of the "body shaming" and abuse she has been subjecting you to, one of your parents or legal counsel must be present. Remember, if the principle insists on speaking with you alone, claim abuse and ask for your parents. Also...cry.   The agency that sent you needs to be informed about the abuse that you are enduring at the hands of these people.    The agency that sent you needs to be informed that an obese principle threatened to call CPS because you are fit and athletic. You need to request that the agency intervene with legal counsel to prevent this from ever happening again.    If any staff member from the school says anything about your size, ask them why they are "body shaming" you. Also say that you were told to contact your parents or the agency lawyer if you were bullied about your "athletic physique" again. Tell them they're making you uncomfortable and that school has become a hostile environment because of their body shaming. That you're required to have this body in order to dance and you don't understand why the staff is so hateful to you. You need to call the agency lawyer. Start crying.    There are no three words more frightening than: LAWYER, ATTORNEY, COUNSELOR. Use them.
