I can understand all of the factors you listed in your equation/decision for not transitioning; the fact that my body would not look exactly like a cis-woman was something that concerned me a lot. I personally know 9 friends who went through transition and everyone of them worried about this. One of my friends was over 6.5 feet tall! She spent so much on her transition and subsequent procedures that she could have bought a Tesla with the money! I told her she was beautiful. :) Another of my friends, who was more realistic in her expectations, spent much less. I know there were certain things about her appearance that bothered her, but I used to tell her that worrying about her appearance was a hazard of being female. Another of my friends owns a media company and her business is shooting video for production companies. Image is important in that industry and she had a big worry about the possible impact that her transition would have on her business. Fortunately, it did not have the negative impact she feared.
Each of my friends (with one exception) completed their transitions regardless and even though they were not happy with their appearance that detail ended up being far less important to them than living life as they wanted.
Felix - If the result of your journey takes yo to a place where you can express the real you then I would say that is the goal - whether you choose transition or not.
