Sophie, you say you are much happier when dressed. In what way? Think about that for a minute.
What are you happy with, as a boy (socially, physically, emotionally)?
What are you not happy with, as a boy (socially, physically, emotionally)? What changes would/could you make to correct this?
Now think about this, you've not been out dressed, not socialized while dressed, probably not met, in person, any other CDs, TVs or TSs (I'm guessing here) unless you are in group therapy.
Now see where you are, where do you want to go, what do you want to be (career wise). Could you do it in boy mode and be happy, or would you be happier in girl mode.
Most of us feel good, euphoric even, when dressed. I could never see myself doing it 24/7, not even when I was a teenager. Some of feel even better when we see our CD image and what can be achieved with a little makeup, etc. And I guess knowing how good you look dressed and hearing it from us doesn't help. But that is not all there is to happiness.
Making changes to one's body takes a LOT of soul searching, which is good that have a counselor to help you somewhat. However, there are probably as many cases of those that have regretted the changes, even afteer counseling, they made to their body as those that do not regret it. So what ever changes you may think you'd like to make, don't make them permanent until you know for sure you won't regret it.
Pretty soon, you
are going to have to venture out in the real world as Sophie to see how you handle it. You keep putting it off, because you a scared, which is very natural. Only then, and after you've answered all the questions you have, will you know who you are CD, TV or TS.
As for going out, I would suggest going with your mom and sister to the mall or shops. Just walk around and try to relax. Sit down for a cup of coffee, then let them walk away a bit while you remain seated. Name a place to meet up, then proceed to the meeting. Doesn't have to be all in the same day, as little steps lead to bigger ones. You aren't going to be able to decide who you are until Sophie can get out on her own.
