It is scary right?
Cause you think you might not be accepted or lose precious relationships...
The truth is that nobody will be glad with your decision, but if they do care about you they will accept you and be with you no matter what.
So why dont you start with the most important people in your life , like your parents or your best friend...
I dont know, im realy not that good at giving advises ...but I have come out to a lot of people , no one was happy about it but everyone accepted me, some did it right away ,my best friend for example ,and others took their time ,my mom for example...
Thats just my story though , you have to be prepared for every kind of reaction, prepare to make sacrifices , you might not need too , but if you are prepared for every possible outcome things will be better...
btw trying to be more feminine , thats a good beginning , the same thing happened to me , you know , all my friends though that I was just gay...
you see , so rare it is , being transgender , it wont even cross their minds,you have to make it clear and be your self,,,do not be afraid...
Still though,,,I understand,it really isnt easy,,,and from now you ll have to try harder everyday , but in the end it will worth it ...
How old are you ? You remind me a lot of myself...like everything you said you are doing , I pretty much have done it myself...
