I think you are a girl inside and will not be happy until the outside matches the inside. You have two options. The first is do nothing and remain the way you are feeling the way you are. The second is to do something about it. That will take getting your parents involved and getting you into therapy. Once they understand what you feel, medical treatment will be come available. It will take several years but in that time, you should be permitted to live as a girl to make sure that's the life you really want.
If you decide on the second option, we can help you tell your parents and if you parents are willing, they can join the board and we will talk with them directly. You now have a very adult decision to make. Do you have so much fear and doubt that you don't want help or are you going to be brave and deal with these problems so you will be happy in life.
I had to make this decision many years ago and I decided I wanted to be happy.
