Talk to your parents about the counselor they want to help arrange. Make sure they know you need a Gender Therapist and not just a counselor. You can hold off transition for a short time, but I'll second what Veronica said, "... I stuffed my emotions for over forty years and looking back, that was extremely foolish ..". Yup, I should have found a psychiatrist who understood gender way back then, but you can do it now.
So, take things at your own speed and follow what fits you. Be aware that your timeline needs to be very flexible, because you could find that it speeds way up as you become more aware of your own being. 🙂
