I don't know how long you've been in therapy and what sort of things you discuss with your therapist. However, everyone has something that makes them feel vulnerable or something they struggle with and all the reasons behind that (it does not have to be "damning") and if your therapist is any good he probably is already aware of at least some of these things. If nothing of the sort has ever come up, maybe what you've been doing is not exactly therapy. Do you find that therapy has helped you with the issues you went into therapy in the first place?
