in context it appeared to me that saying "become transsexual" was just Wild Flower's way of saying "if I transition" (the verb). Anyway that's how I understood it.
Just about everyone who does transition faces the risk of rejection. I completely lost most of my (birth) family. I still talk to my mom but none of my 3 siblings, or any other family. At least I didn't have a wife or any children to put through it, but I did lose 2 of my best friends, both female- I took "him" away from them slowly by degrees and finally it just became too much for them to bear anymore. It hurt them, and it hurt me- but I had to know that if I hadn't I would have ended up in a far worse place. So I cried, and I moved on.
Transitioning isn't something to be taken lightly; there are many obstacles that some never surmount, or decide they'd rather not. The only real cure for me was major surgery, so these aren't easy decisions to make. But only you know who you really are inside, and only you know can hear the voice of your own heart and follow where it may lead you. Friends, even family, may come and go, but you have to live with yourself for your whole life, and it isn't being selfish if you choose to be happy, no matter what that means for you.
