Welcome! We do have some transgendered people here, but evidently they haven't had a chance to see your post. When it comes down to it, I think we could say you're having "identity" issues. Your parents never let you just be who you were and even to experiment with what you like and don't like.

Are you in a position to see a counselor? I think it's very important that you talk to someone about what's happening with you. You are certainly not alone. After some therapy, then you would typically try out living the life of the gender you believe you truly are.

Let's hope that someone with this experience posts soon. Meanwhile, hang in here. You don't say how old you are, so that might make a difference in what approach could be taken.
