Many of us went through the same confusion as you are, which is why we say do not rush things. You could end up doing something that will change the rest of your life in a bad way. Keep in mind, finding out what you are may only be the beginning of this journey, no reason to rush it.
In the meantime, you might want to take a look at some of the threads in this forum on clothing and style, they may give you some ideas on what you can do to feel more comfortable with yourself and not do anything permanent or stepping too far out of your comfort zone, this can be very therapeutic, but go slow. You do not want to freak anyone out, much less yourself.
I would ask your therapist if she has treated androgynes or Ts before, if not, you may want to find one who has. She may be fine for your other problem, but not this particular one. Both problems could even be related, but I am far from an expert on this. I would worry that she may not be able to properly help you. There are some pretty bad stories of androgynes going through transition and finding it was wrong for them, you need to be very sure before you do that. Right now, I would say you are not ready to make that decision.
