Welcome, hiddendress. You have found a safe place to talk with others. We do watch over our young folks very carefully. We have several minors who come in to #chat most days, too.
As far as telling your parents goes, I don't know how wise that would be if you are a crossdresser. Might it be better to wait until you're in college? If you think you are transsexual, then maybe yes so you can begin counseling with a gender counselor. We have lists of known counselors by state in our Medical links.
Best wishes
Granny Robyn (71)
