My son has always been different. He always struggled in life. Always had difficulties fitting in. We, my wife and I, have always been there for him. It took him, us and some professionals a long long time to figure out what was wrong with him. The clues where there, he always tended towards female stuff. From dressing up, his interests and even his behavior. Everyone was just to stupid to count one and one together.
Finally, shortly before his 18th birthday we all finally realized the obvious: My son, or better said my daughter was trapped in the wrong body. So we helped her to change that. Helped her in her transition. It took some time, but slowly and steady she turned into a stunning good looking young girl. It probably was the first time in my life I ever saw her really truly happy.
