I'm sort of goping through this problem now with my T.
Often I dance around the issue of my experinces with abuse, and when I do talk about it, I have a tendecy to edit the content the point where I'm not sure I'm explaining the situation right.
when I first started therapy, I wouldn't even utter a word about my past abuse...but now that I realize that being Vulnerable isn't a crime, I can open up a little more.
Its like jumping into cold water; sure it may shock you at first, but as time goes on you'll get use it...you just have to try (at least once).
that's my two cents at the least.
Hope you get that confidence you need esthervirtue
