Hi Francina. I did'nt start my transition until my late 40's. I am a transman, but we all go through the same hardships. Possible loss of family and friends. What it comes down to, is, only you can answer your questions. If you know, beyond a shadow of a doubt, that you are female, then, no matter what you do to try to cover it up, it will always be there. And, you will have to deal with it. And, there are people here that will support you, if you make the choice to transition.
If this is just something that comes up for you, off and on again, then think long and hard about transitioning.
Transitioning is one of the hardest things I have ever done in my life. It is not something to take lightly.
