Im glad you have posted this, I have my first CAMHS appoitment on March 11th
Sorry that I can't answer your question but I just want to say I hope CAMHS helps you and that you shouldn't be nervous because they are there to help. Also I think they won't tell your parents anything you have been talking about without your permission. I have had help from two proffesionals before and they never got in contact with my parents without asking me first.
