I should tell you, though, that HRT is not something to take on lightly. Like all medication, it's only to be done when there are no more options that are safer, especially so with HRT. After a few years on HRT, you're on it for life one way or the other, and you'll need to see a specialist periodically to make sure your endocrine system is okay. Even if you decide you want to have male hormones again, you will need to take male hormone pills. You'll also need to take damn good care of your liver, which means you need to reduce or give up smoking and drinking, or else you're going to likely have a lot of liver problems either now or later in life. This isn't some fun ride where you can get off wherever you want, and if you decide to go back, you're stuck with whatever breasts you've grown, and can only get rid of them with surgery.
If you're dead serious about this, though, (and by dead serious, I mean that you're just about willing to kill yourself over it) you should find a mental health professional. Make sure that they're qualified to make diagnosis and prescribe psych meds (doesn't have to be the same person, usually a Psychologist or a Psychiatrist, although there might be some GPs or endocrine specialists who are comfortable prescribing hormones).
Lastly, though, if you're doing this for anything less than to make your life livable, then I can't say that HRT will make you happy. You won't stop being a freak, because we are all freaks. At some point, you need to look into the mirror and accept some things, embrace them, because otherwise no amount of surgery or medication will ever make you happy, and you'll eventually become Joan Rivers.
