Do NOT refrain from transitioning because you don't want to cause a hassle to others! Living with dysphoria can cause serious mental and physical harm, and that would be a far greater hassle in the long term! What is important is that you recognize the problems you have, and take steps to dealing with them.
You are still young, so take some time to work though these feelings. You are certainly 'on the trans spectrum' already, from the things you say, but it is important that you do not inflict upon yourself irreversible changes that you later regret. Transitioning can and usually is very tough mentally, and takes a very long time.. I don't mean to scare you away from it, if this is what you need to do then you should and I will certainly do my best to give you any advice I can!
You have already made the first step I tend to recommend, which is dressing as a woman in private. Its how I got started as a teenager, and it always made me feel so happy and excited -and often sad, that I couldn't do it all the time-.. Next step I think would be to try and seek out a gender therapist, or and existing therapist you have for other reasons that you are comfortable talking to. I also think starting to present as female online in certain settings is a good way to get used to the idea of people treating you as a woman. How does it feel?
Also, consider if you have any discomfort in your current body.. Do you often look at it and wish it was that of a woman? You already tried to grow breasts, so I imagine that to be true.. When it comes to Aspergers, I am clueless.. Sorry!
