Hi Diana and welcome.
Being on the other side of the Pacific I can't help with doctors, but California seems to be a good place to live if you are trans. You have come out to the most important person; yourself. From here your path will gradually become clearer. Sometimes the road is bumpy, but at least you have found the right one.
I started by reading everything I could get my hands on and found a Gender Therapist. Until I actually started making changes I did a lot of discrete people watching at work and elsewhere, to see how women did things different to men. As I had expected I actually had a lot of the body language and mannerisms lurking just under the surface. I expect a lot of others had the same feeling.
Karen.
