When I went full time last month, I expected support but not to the overwhelming degree that I got.
You'll be fine I think. The world is different today and despite the gripes about Caitlyn Jenner and trans visibility, people seeing her in the public eye show us that transgender people are here and we aren't going anywhere, and we deserve your respect.
I got questions but they were more along the line of how do I feel, how is my family etc. But after a few days they simply died down. Management has been very good to me and they respect my space but also treat me fully as a woman. Almost no one asks questions now.
People have congratulated me, sent me flowers, and even struck up conversations in the restrooms. I also have a regular breakfast chit chat with my teammates who had pretty much slid into social isolation with me, but now they feel more comfortable with me. One of them was the only woman on the team and she was overjoyed that she now has company.
So relax and enjoy the ride. It's going to be good.
And do expect occasional misgendering and deadnaming because people will not get it all at once. As long as they sincerely try and correct themselves when they slip I am fine. You should be too.
