You know it would be just so much easier if we could just know for sure if we're trans. For me it was not wanting to die as a guy. I always sort of knew inside deep down, who I was, but Fear of coming out kept the real me bottled up for a long time. When I did finally come out, well It was more Gee, so that's why you were weird all the time (from my brother).
So a question to ask yourself. Tomorrow morning when you wake up do you want to wake up as a boy or as a girl. If so why.
It's best to be sure of who you are, and no matter the answer, we're always here to listen.
