I can relate to your question.
I never felt like I fit in or belonged. I did not like guy sports or aggressive behaviour. I liked hanging around the girls. I remember wanting to be a girl and like the girls. I remember constantly going through my mom and sisters things and wearing their clothes....putting a bra on and going out to play in my sand box.
I developed a few guy friends that were gentler, deeper and different. I often wondered if I was gay.
I grew up with a high level of emotional sensitivity and emphaty, not like guys I have known. I also grew up struggling in school feeling different, and likely with a learning disability, like dyslexia. I eventually suppressed my feminine side.
My family was relatively poor and worked 7 days a week. And I begrudged teachers, kids and my parents...I became determined to prove them all I was good enough and could be successful with an amazing life. Well 50 years later, I have achieved a great family, career and have a great spouse, who I envied (I know realize in hindsight). The problem is the suppressed feminine me has been there constantly, beneath the surface and peaking out more and more...when I idolized and wanted to be like women I would meet, when I would dream and think constantly about ways to get away with wearing women's clothes, let my sensitive side out periodically, cross dress for brief periods.
Now that my life goals are achieved and my children don't need me as much, and I at mid life, I have found myself on a 2 year journey and nagging feeling about my gender. I have always wondered who I am and why I was different. I started reading about gender when the national geographic came out, hated my body hair and started to do laser, lost my mom and last parent....and 7 months ago, had a gay friend explain transgender to me...and the difference between gender and sexual orientation. It was like lightning struck me.
My life has been upside down for the last 7 months as I relive and make sense of who I am. I now believe and accept I am transgender, and am making small steps forward while figuring out how to handle and mange my life. On one hand it feels great and like I finally have an answer, and on the other scary and uncharted. My spouse knows and is supportive so far.
Lots to figure out. I hope this helps, and anyone please challenge me if you think my diagnosis is flawed.
