As for the guidance counselor, they would be able to keep it confidential for you. The only time they would have to report it to your parents is if they had reason to believe you were a danger to yourself or others, or if there was a reason to believe you or someone you know who is an elder or child is being abused. So, if that's not the case here, I think you should try going to the guidance counselor, since they wouldn't be able to tell anything to your parents without your permission.

I do that with my friends, too. That's where I DEFINITELY have to remind myself that if they're continuing to hang out with me, they must really like me!
