Yes, I have noticed that a lot of my anxiety has decreased when I just let myself be the girl I am and don't worry about what others think. In fact a few times when I had to face stressful situations I have mentally turned things over to my 'girl side' and let her deal with the situation. Usually that has worked. So, yes, I can relate and I see it as part of us growing into our true selves.
Of course I still deal with anxiety arising from various dysphoric situations, but that another issue.
