Dee,
I remember talking to my therapist about going full time. I was concerned that some situation would have me wanting to scurry back to the safety of 'him.' I worried, I went full time, and almost 9 months later I have never felt that need or desire. What you are doing has to be done. You have to go through this time, these feelings. You will get past it only by stepping up to the big, bad beast called fear and knocking it straight across the jaw with your purse. (Now there's a picture.) You will find great joy being yourself. You also will have times where you want to crawl up in a ball and cry. Just remember, it will get better and better.
I had a training the last two days for work. I was with strangers. No one knew my story. I had to get up in front of everyone and act out scenarios of dealing with behaviors. The first day was okay. I was terrified. The second day, I lost all ability to have anything close to a feminine voice. What's the next step above terrified? But I got through it. It didn't kill me. If anything it provided motivation for me to figure out why the voice comes and goes. My point is, I don't think anything like that will have the same effect on me again. Whatever it looked like, I handled it. I would suggest that as something you can say to yourself. "I can handle this."
Good luck and enjoy, Girl.
