Speaking as someone who is doing this, you are right - it is a hell of a lot to go through all over again and in some ways feels harder than originally transitioning in the first place. If you feel that it is too much trouble and you are relatively happy as you currently are then you just have to weigh the pros and cons for yourself. Also, you can do what I am doing and over a longish period of time making a few moves in that direction if they feel right and if so try a few more. I guess, more than anything, just keep an open mind and be true to yourself. No decisions should be made overnight. Again in my case it took me a few years to decide this is what I really wanted.
