I can see this from a different perspective Sweety. I had a friend that asked me about therapy. What it was like and what to do type questions. She was new to my area of town and was afraid that she would get lost. She also was afraid that she might not be able to drive after the session.
I told her I would drive her to the first appointment and go in with her till she was able to meet the T. Then I went out to my car till almost time for the appointment to end. I was in the waiting room when she came out. It just helped her through her fears of that first meeting.

When her session was over T came out with her and they were laughing. T thanked me for bringing her.

My thoughts for you right now is wait till you have the first 2 transition sessions before you worry about this.
