there seems to be no reliable resource for minors. all of them involve notifying your parents in some way or are there just to prevent you from killing yourself. there are no resources i could find, online or in person, free or paid, that provide private care.
I think you should call them and find out. Worst thing they can do is say "talk to your parents" you know? Just tell them that you can't talk to your parents about this, and that you need a resource for teens.
And call a different state's number. No rule against that.
