Cire, the first battle you need to face is with yourself. As strange as that may sound, until you figure out, face, accept, or deal with whatever it is whithin you, your will be going in circles until it is resolved. I'm still fighting that battle within myself after 39 years, even after 5 mos of hrt as well. I hold onto hope and that small fire way down deep in the pit of my body just under my heart that I'm doing the right thing. One thing I can say is if there is any doubt, then run away as fast as you can. This is not a game. Only you know if it is for real.
Hrt can change many things, but it will not change bone structure after puberty. Most of your upper mass is muscle and that will be lost giving you a more feminine appearence usually. Nobody can say what it will do for you. I've seen some TS that have been on HRT for 5 years and I can only shake my head and think "You have got to be kidding. If you cut your hair and grew a beard you would be a man!!" Others turn completely into women and you wouldnt know the difference. Genetics, age, perhaps even luck will determine how you do.
Before you start, you had better know what you are doing and what the long term ramifications are. Its for life. Do you really want to live as a woman? Think about the daily life of a typical woman. Its not easy...lugging around a purse everywhere, always being scrutinized for clothes, hair, makeup, weight, body, skin complexion, shoes and so on and so forth. You may be treated nicely but your words have little to no value around men. They don't care what you have to say as long as you have big tits.
You may want to reconsider having kids as well and the long term effects it will have on you and them. They have to go through transition with you as well. Then you may end up paying childsupport on a typical woman's wages wich barely pays enough to survive on in the first place. Unless you just cannot take living as a male any longer, then run away.
I hated looking in the mirror at myself and could not stand that ugly horrid looking body and face one more day. It was either eat a bullet or try something radical and just try to transition. From what little you have written, I'd say you are more curious than anything else.
