Jennifer,
I don't think the feeling ever goes away,at least for me it never does. I'm 53 and still the feeling is strong. When I'm not dressing then I'm thinking about it , looking at other women to see how they dress and carry themselves and wondering how I would like in that outfit. I have purged so many times in cannot count, but I regret every time I did. Some of those cloths will never be able to replace. I finallly made peace with myself and am happy with who I am . The only regret I have is not to be at this point alot sooner.
We all have struggled with this dillemma at one time or another but in the end it is all up to you how you control or resign yourself to the fact that you are a CDer or TS and probably always will be.
