Hi DiAnn, I remember the emotions you describe. All my life I felt I was in control, I was strong. Then, this anxiety thing happened. I too felt as if the "real me" was gone. Now I realize that the real me is still here. The bravado that I used to think was me was really only an attempt to protect the scared/insecure person I was. Like sky said, waking to yourself is really the first step to becoming the person you are.
Be kind to yourself as you work through this program...reading your message, I had this overwhelming sense of lack of acceptance of self...lack of willingness to sometimes not be in control. I can remember those days clearly...but in a fairly short while, I've made progress in trying to be more accepting of myself (some days are far better than others).
Our traits that make us anxiety-prone can be real blessings if used properly. We are generally sensitive, thoughtful, creative considerate people. Unfortunately, we used those skills to scare ourselves. In day-sized chunks, I'm trying to get to the point where I'm able to be who I am while acknowledging my unique strengths.
