I understand your situation, I remember when I decided that I couldn't live my life as a guy any longer. I first started with gp dr, got him to prescribe me hormones, and doing things on secret like, then I decided to tell friends and my mom at first they went with it sorta untill they realized I was serious, so my mom contacted tthe dr and told them I had mental issues and that I was unstable and got him to not prescribe anymore I was 19-20 then. my co-workers started to pull away from me, and then it got to the point of being dangerous so I went into hiding witha friend, people were genuinly out to get me and possibly hurt or kill me because I was different. Eventually what happened was I met someone online and went with them to a club, she was a gg, and we were meeting with a tg, well i went along and after conversating another tg offered me a room to get away and start over. I took that chance and went. had a hard time getting a job but eventually did,it was a bs job at night with very few people, and it allowed me to make money to go to a real dr and get the hormones I needed, and also the funds to change my name and such. I then found a new job and no-one knew about me, and I kept it that way. Basically started a new life.
do I miss my old life I ran away from? yes a little, but not enough that I have any regret what so-ever.
being tg is dificult, when you decide to finally come out,decide to act on, or whatever you have to be prepared to change everything and accept the fact that you will more than likely lose friends, but then you need to ask yourself this if they were really your friends than they would of been there for you no matter what.
I still have a couple friends from when I started transistioning, do they understand being tg? no I doubt it, but its been such a long time They dont remember me even being a boy any more.
I think if you are going to make the commitment, be aware of what you may lose, and if you havent done so already work on name change and such, so no one knows you as anything or anyone else, and second dont tell nobody that your tg. and if you do be 100% sure they are true friends.
You will make new friends I am sure but so times you have to go back to nothing to finally have something.
