Well, I do have one thought about it. If you were to have counseling, your parents would perhaps know that you were having it and the expectation should be that your discussions with your therapist are private and not to be shared with your parents.

If you were to go in this direction, I would suggest that right up front you reach an understanding with the therapist as to what, if anything beyond any signs of immediate danger to you or others, he/she would consider revealing to your parents.
