The times I limit my sharing is because I can't wrap myself around the thoughts to clearly present them. They are still in the jumbled state. Sometimes I skirt the issue to try and bring clarity to the thoughts and maybe state them but usually it takes another week for me to clean them up.

Another reason I sometimes limit my discussion with the therapist is I know what he is going to say, and I don't want to hear it again. I know this is probably faulty thinking because he may not say what I think.

Just last week I became suicidal and was seeing my therapist the next day. I didn't call him because I didn't (couldn't) get into it without getting more upset and risking a hospitallization which would really disrupt the whole cart.
I did share it with him the following evening. I did manage to move on and distract myself by sorting beads for three hours. No sleep that night. But I made it through.

I get what you are all saying about the trust is key. I do trust my therapist.
I just need the control of my own choices sometimes. I guess I look at it as a way to manage the amount of pain I walk away with from the constant digging and rooting around through my gut and head.
