Thanks for all your responses!! I even mentioned this to him already. He said a lot of people have trouble opening up (the obvious) but he followed by giving me an example of a past client who wanted to disclose everything. He said he was a patient for 30 years and got much better. Ok-so I didn't think to ask him at the time-but when I left I thought-how could someone need therapy for 30 years??

Thinking, do people who want to tell all have some kind of major issue?
You know, I have trust issues like many. I've been through a lot of abuse, but I do think most people generally have good intentions. But I don't automatically trust everyone-for ex., coworkers, strangers. I've been abused by authority figures in the past, but for some reason, I'ts almost as if I'm "automatically" trustful of people who are authority figures, or who exhude authority. It doesn't make sense. Authority figures (I include parents in this description too) are mostly the one's who were abusive to me.
Christina, my mindset seems somewhat similar to yours-I want to get moving, make progress! I'm super motivated. No, I don't feel bad afterwords for having said things, just the normal embarassment at times I guess, but I recently had an experience w/another T w/with the same type of background-I told him everything in 3 sessions--and he didn't want to treat me. I've had 3 Ts in the past, and never had that happen before. So I guess I'm scared of his reaction to me. I'm scared he wont' want to treat me.
For example-If someone were to disclose everything in a month, wouldn't they seem to have more issues than someone who took 2 years to tell everything? I guess I'm a bit paranoid since that last experience, since I 've never had these thoughts before. I'm thinking the T must be thinking - wow, in 3 sessions I find out she has all these issues-I wonder what else is there! In reality, in the 3 sessions with the last T, I told all major issues-of course, millions of details are not addressed, etc. But generally, everything significant as to things I've done and things that have been done to me.
I feel bad for those who want to tell but can't. That sounds frustrating

. I'm really down on my self esteem, but yeah, courage is one thing I can say I have. That's something.
It seems it can be dangerous to be too trusting. I was recently in a sort of minor car accident-well a guy in a truck just moved into my lane and dented the back door of my car. He happened to be a cop (not working at the time). He asked me if we could not put it through the insurance. So I didn't call the police or insurance. Sent him an estimate for the damage(and he did call me back). But that's wrong-I could have been screwed big time. (Well he still did not pay me yet but he seems to have the intentions) Not an example of doing something dangerous, but because he was a cop (showed me his business card/offered to show badge) I just automatically trusted that he would pay me for the damage. But there are bad cops out there. He could have later said--I've never met that person in my life....I mean, I was stupid for not calling the police. I'm unsure of myself sometimes..
You are all really helpful to talk to.
