There are many ways to transition.
A good gender therapist is a start and the process can take years so now may be a good time or some time of your choosing. The important point is you can be in control of who you are and the timing of the changes.
Yes it is scary and you will adapt, as well as those around you.
Kate Bronstein has a book called 101 reasons not to kill yourself. In the book there are the 7 things that are the most important and I use them. I use several others too and they help a lot. Perhaps you could get a copy of the book.
Some of the things I have done i can not believe I am still alive. I am glad now I did not succeed but when I was in the middle of despair I could not see a way out. Gender therapy is the beginning of finding out what you want to do and how a and when. Just taking the first steps helps.
I cry a lot too and it is the estrogen, although I cried a lot before E too

Perhaps I am not a good example. Guys cry, mostly in private. Sometimes they channel their emotions into rage, rather ugly to witness.
You are who you are and right now your mind knows you need a change, to what extent and depth and when is all part of the journey that you control.
Hugs and I hope you see a gender therapist. If need be say you are seeing a therapist for depression which is true. Just make sure it is a gender therapist with experience.
