Physical at doctors coming up, need advice...?

Your doctors job is to keep everything confidential under ur say. Your doctor isn't aloud to tell your parents anything except for the basics or if you have a serious illness. The only way this cud be serious is the fact that its illegal. Idk if a doctor has the athority to call you in. All I know is even if they detected anything they aren't aloud to question you about it if you don't want to cuz u have tht right...and they aren't aloud to tell ur parents or ANYONE in tht matter for confidentiality reasons.
