It is where I am transitioning and so far things are going great (4 months into HRT). The mind does go through interesting things, but mainly positives (like I have less anxiety).
Only three things are causing "problems".
The first is the laser hair removal for the beard (it knocks me out of commission for a few days... I have a really bad reaction where everything gets HUGELY swelled and needs a lot of attention)... but, I can work around it mostly by timing it on a weekend where I have a couple days to recover mostly.
The second is the emotions. These pop up now and then (but are mostly under control). Though, I have had to escape from one school function when I was having a really hard time controlling things. I'm really worried that I will get some overly critical feedback on my work or caught off-guard with something and I won't be able to control things without a place to excuse myself to (randomly getting emotional is just socially odd

). But, other than that, I actually love the emotions (they are interesting / new / fun).
The third is my increased desire to be social. Normally I could simply sit and focus on work alone... but now I actually feel like going out with people to do things. Not sure if this is the hormones (I am pretty confident it is). It isn't that big of a problem, just need to work harder on trying to force myself to work more

As for coming out. I have told a few classmates and one instructor... and so far everyone is very open. Actually, the instructor I told became a lot more agreeable / understanding with me (so I think I could use that to my advantage with other instructors if the reaction is one of "I had no idea the things you were going through!" type of thing... which seems like it could help smooth things out if transition causes an unusual amount of problems that need to be explained *like the entire missing class thing from laser, currently I say it is simply a bad reaction to a medical issue and excuse myself from class that day*).
Overall, I think things will work out just fine

I am slowly coming out to more people, so try and have a base of people who know that can help dampen any overly dramatic reaction suddenly being "found out" my cause (when you go to someone with the "juicy news" and they have known for a long time and are cool with it, it kind of takes the wind out of your sails

).
