Starting my new job tomorrow

So tomorrow I start my placement/job at a group home. It's for my SSW program. When I handed in my stuff to my new boss she was friendly and that was cool, however I'm for now legal name is on the paper so I came out to explain why it's there. She was cool and was nice again, she also told me she had no idea I was transgender(yay) and that she won't tell anyone. So I start tomorrow and no one knows I'm transgender and I'm excited and nervous. But I really hope it goes well and that no one finds out that I'm trans.
