Keep in mind, transition isn't an "all or nothing" type deal. Your aim should only ever be to find your own happiness. That's all. Just take baby steps toward what you feel will make you happy, eventually you'll find where you fit. Some people take the approach of immediately casting off their old identity overnight, others go very slow. I don't know which approach is right for you. Personally, I transitioned very slowly. I had been on oestrogen for 2 years before I slowly started to dress more androgynous. I wasn't sure where I was headed, I wasn't even sure what "feeling normal" would mean to me. Eventually, people started perceiving me as female more and more, and I preferred that. A lot of trans people have a date that they went "full time" I don't. I have no idea when that actually occurred. I just took little baby steps. This, for a while was hard because I felt totally genderless in a gendered society but, ultimately it was an incredibly smooth transition (not that there's anything wrong with having no gender! I just say for me personally, I found that hard). It left me of the opinion that "slow and steady wins the race"
If I could go back in time and talk to myself 6 years ago, when I was in your position, my advice would be
Don't stress, be patient, its a long process, its not a race.
Get healthy, don't smoke, don't drink too much. Its easy to to drink yourself to numbness, all it does is delay your feelings by a few hours.
Don't be afraid to talk to people, what you're feeling is normal.
If you have any queer friends, talk to them. they wont know what you're going through exactly but, they'll understand the feeling of isolation caused by being different to the majority.
