Answer:
Well, I am a christian so I believe in God. This is just me answering a question.
Sadly, this type of stuff has been around for a long time and I too have struggled with my sexuality. The brain does not simply "process" changing genders. Your consciousness is constantly trying to tell you to stop trying to change. People get pressured. They get sick. They let society control them. Personally, I still don't fully understand this "life" thing. I don't think I ever will. I am what some people call a "tom-boy" and I am beyond okay with being called a "tom-boy." Why? Because it is just a label and I am who I am. So to think that your brain "processes" this "idea" is really just that...an Idea. Our brains cannot process something that people in general cannot understand as a whole.
