I'm continually dealing with this issue also--afraid to share the thoughts that plague my thinking for fear that my T will then know how warped I really am. I avoid things that make me look bad or disturbed Which is totally ridiculous because: 1) after over a years worth of appointments...she kind of already knows... 2) that's what I'm paying her to listen to.

All I can say is just keep trying. My progress has been very slow in this regard.. but progress none the less. If you have a good T and are really trying to engage... the darker areas of you will eventually be shared.
