School (college) counselors have the same laws that govern them that any mental health professional has. In point of fact, they are not allowed to give your parents information either medical or behavioral health without your express, written permission. Same as a hospitial if you are of legal age. And most colleges automatically make you an emancipated minor as soon as you enroll provided you are not living at home. Even then most do.
Lotsa parents fulminate about that under the rubric of "I'm paying I have a right." Well, no you don't. No more than you have a right to know what someone on Medicaid has going on with his health even though it's paid for with taxpayer money.
Information must be kept confidential. You'll be asked to sign consent forms and waivers of release before any info is released. Same is true of your grades, etc. You can thank the Buckley Amendment of 1974 for that: Phillip Buckley of NY, not William of Connecticutt.
Go see a counselor at college. College is a wonderful place to transition if you can do so and maintain your studies. Provided you aren't going to a church school you may well find that the administration will be much more open and helpful than the public officials in your state are likely to be.
