First of all never, ever give up. What you have read on this thread is mostly good advice I would suggest that you go back and re-read it again, and think about each post and decipher the good, the better, and the not so good.
What you are considering is at best, a difficult undertaking. Just how difficult depends on how smart you are and how well you are able to distinguish between 'good' choices, better ones, and 'not so good'. Luck and fortune will also play a roll.
I think that if you spend enough time around these forums, you will find that there are a lot of people that will tell you that there are lots of ways to be 'trans', and that 'transition' is different for everybody. They will tell you that there is no "right way" to transition. In many ways they are correct, and it stands to reason; we are all different and we all start from a different set of circumstances ranging from age to socio-economic status.
I think what is important in your case is that you are young and you seem to have an excellent understanding of your current situation. You appear to highly self aware and this is an extremely vital characteristic which in my opinion should be exploited to the MAX. You need to clearly understand just who you are, and more importantly who you will become. Once you have that clearly in your head, figuring out just how you plan to get there is easy by comparison.
