Agree on the comment above. Consult with a lawyer about it. Maybe there's still away for a restraining order after he gets out in prison. There are free legal advice online like (link redacted). And its good also to talk with groups that you can rely on.

There's a confidentiality between the patient and the doctor. Doctor is not allowed to divulge information unless ordered by the law. So you don't have to worry about it. But if your situation badly needs your parents guidance, then don't be afraid to tell them.

Best of luck,
