I went to a psychologist for depression (my parents knew I wasn't doing that well, so they were fine with it) and after a while, when I trusted her (the psychologist) I came out to her. Seeing her really helped me understand myself, and I was finally able to make progress in the direction
I wanted. I saw a gender psychologist and an endocrinologist, my parents even drove me to the appointments, and they thought it was for depression (well it a ways it was, so I wasn't lying

).
I was very scared about coming out to my parents (they turned out to be very accepting though

), I'm dependent on them, I didn't know how they would react, they could stop taking me to my appointments, or just kick me out of the house. To jenny I'd say NOT ALL PARENTS are trans friendly or aware, getting support from doctors/therapists/etc can really help with coming out to your parents. If you are dependent on your parents, and are positive they will 1. not kick you out, and 2. help you get a psychologist for gender issues, then by all means go for it. If you aren't sure then I'd be wary of it, and see if they will take you to a psychologist/etc. All the psychologists/psychiatrists/etc (whether they were trans friendly or not) I've seen kept everything confidential, and my parents had no part in my therapy if I didn't want them to (even when I wasn't legally an adult).
