Sounds like something I regret to. I was hated at junior high school. Christine Jorgensen was brutalised(keypad stuck) by the press. My Mom found out that my cousins favorite blouse was in my bedroom closet. She told me that if I had been born a girl that she would have named me,Penelope. There hasn't been a day that passed that I wished that I would have told her that every nite I would pray to wake up a girl with no memory of ever had been born a boy.
Just do it again by having clothes in your bedroom,let her find them, then have a discussion with your Mom. Your still young yet.
She seems to understand.
Best wishes and have a lovely day.
