I work in a female dominated field, but I'm lucky in that it's accepting of gay men, too.
Because I don't want to transition *at work* and deal with coming out to clients, however, I recently started T and am giving myself about six months to get my life together (wardrobe, paperwork, etc.). Then I'm pulling a Houdini, skipping town, and doing what I do now, but in a different location. There will be a temporary pay cut, but I can bounce back.
If you don't want to wait until your degree is finished to transition, can you stay within your field but plan a transfer to somewhere else? Do the same or similar work with a different company?
I make great money where I am at and my colleagues are lovely, so it pains me to leave. But ultimately, going through with transition, living a stealth-to-my-choosing life, and moving to an area where I would have more social support is better for my mental health in the long run. Waaaaaaaaaay better.
Good luck.
