I urge you not to fly right into testosterone. It sounds like you are very unsure right now.
I had to ask myself if I was crazy or not wanting to change my external appearance to a girl. I finally decided I had to seek a therapist to help me decide if I was crazy and help me decide my direction. It was during my counseling sessions that it became clear to me to go forward with my transition. I was never told I was crazy, even after I asked my therapist if she thought I was.
Middle ground, although it no longer am.
I go by JAKe and Jeri, too.
