You are young and you still have time to think and gauge the feelings and think things over and over again.
The only thing that I´ve been always warning about, that don´t let that thinking and supression take you too far, to the point where there is then only two options left, either I kill myself or I transition.
I was in that spot last October and everything was ready for departing this world, money things arranged for people to sort out after I´m gone, insurances cut off, method ready and thought out. But one morning I thought, that I never really even tried to live as myself. Thought about it about half day...and transitioned immediately. It´s been now about exactly 9 months since that and most of the things I wanted have been now done, surgical, name etc etc, only the legal gender pending, but should happen within next 6 months.
I´ve absolutely enjoyed the past 9 months. No I didn´t pass at the beginning, perhaps I still don´t, I don´t know and I don´t care. I´m alive and people who perhaps stare and smile and laugh...don´t know that I very well might be dead, if it wasn´t for transitioning.
I didn´t ask to be a trans woman, it wasn´t my choise and I really would have not chosen anything like this, if given the chance.
So, whatever you do, don´t let it go that far, because even when I´ve enjoyed every moment, it has been very taxing mentally and has taken every penny that I had and more.
But, it´s just money. I´m alive.
