I think everyone has different levels of trust and that plays a lot in to how much you tell your therapist. I have been seeing a T and P since August and have been diagnosed with being cyclothymic which is mild bipolar. I am just now starting to feel more comfortable with my T to the point where I can open up a little more about my life. At first I felt like if she new everything upfront I would be put in some sort of home or hospital. I now feel that I have shared with her the basic facts about myself and can now start to go more in depth with her about things of done and behaviors I've exhibited. I believe that everything with me must be done in small steps and that I'm not going to fix everything in a day so by going deeper and in more depth with my T I'm just building more trust and taking more steps to understanding and controlling my illness. I have been keeping a journal which I share with my T and that has helped me alot in expressing, sorting, and coping with my moods and thoughts.
