Suzi is further alongside than I am so she can probably give your more pointers.
For what it's worth I've gone from about 210lbs to 180 in 9 months and started laser like you 3 months ago. I found a therapist early in December and started hormone therapy early in January. I don't plan on being full time for a while yet. I have a receding hairline, so I have to wear a wig.
Like you I went through a 'what on earth am I doing?' period and managed to get through it and out the other side with more confidence than before. I started going out as Joan in November, and though I stand out the majority of people are much too wrapped up in their own lives to care that much about mine. Realising this was a pretty big step and quite a weight off the shoulders.
I don't know...moving forward with this wasn't something I could avoid, and at first I wanted to be perfect and passable, and then I realised this was going to be difficult so I lowered expectations and it felt easier. It also all became a lot more fun, and life is more fulfilling than it has ever been before.
I expect more bumps and crashes along the way, but on the whole I'm happy with where I am and where I'm going to.
I hope that helps
