What you do in this situation is entirely up to you. If you really don't feel like you can continue living as a girl then it might be worth it to keep explaining it, sometimes people in our parents' generation struggle with the concept of transgender because it wasn't acceptable when they were growing up. It might also help to tell them, if you choose to try this, that gender identity and sexual attraction/orientation are completely separate so you can identify as male and be attracted to males. That would mean that if or when you transition, you would go from identifying as a 'straight female' to identifying as a 'gay male'.
