I second Jessica's post and invite you to PM me, too...
Therapists these days are a very different breed, and a good gender therapist will talk to you, listen to your concerns, and help you. My GT is very practical and helpful. She understands that I am going to her to get a letter, and has offered her services in going over a number of legal things like name changes, etc. She has built a list over the years of trans friendly doctors *and* the ratings her clients give her.
So I know the endo she recommended is a good one; she's sent many trans* men and women to her over the years and has gotten glowing reviews. I've recently asked her to research trans aware GP's in the area and she is working on that for me. She understands my concerns about being tall and passing, and is setting up a meeting with a successful, tall trans woman she has helped who has helped her in the past.
Also, she has never once asked me to tell her about my mother. After listening to my reasons for being there and being reassured I know what I am doing, she is focused on who I am and where I am in my transition, and how to get me to where I need to be.
That being said, there *are* ways to transition without a therapist (read the WPATH standards), but given the help my own has been on a purely practical level, I can't imagine why I would want to transition without one.

PS- I see Miss Bungle weighed in before I could hit "Post"... still posting this because there are *some* insights left...
