Transition is a brutal process no matter how you slice it because of ONE thing. The social aspect. Sure the surgeries, and electrolysis, and yadda yadda yadda, there is physical pain but NOTHING is more difficult than the social transition. It is everything.
The day after you pull the pin, your life as you knew it is over. If you're a late TranSitioner, then you will NEVER be free of the dude you used to be. You will NOT disappear into your new life as a woman. You will always be a transgender woman and you will never forget that you were a man for most of your life. Most of the people in your life will never forget it either.
Younger people have the advantage of more time in front of them then behind them, as well as physical advantages. I don't have advice for young people except; be true to yourself, you ain't gonna be young forever.
Transition takes away everything and only gives you ONE thing back; Freedom. Don't transition unless you think that's a good trade.
For me the freedom was worth everything.
