My T doesn't even ask me if I'm thinking about hurting myself. She just tells me that I am thinking about it. I might not be right that moment, but it never completely goes away for me, even if I think it has. If I have specific plans, I'm not likely to volunteer anything about it until there is more of me that doesn't want to go through with it than that does want to. I have to have enough of me that is willing to be stopped first.
I self-injure too, and T knows all about that. Usually what I do is pretty minor. Last time I had emailed her and mentioned that I went out and trimmed the roses without gloves, for example (as that was better than the other thing I really wanted to do). Then in the session I was talking about messed up thoughts, and describing them, and one that I identified was feeling like I deserve to be hurt. She asked for a specific example, and I couldn't think of one and said maybe I haven't had that thought in a while. Then she mentioned trimming the roses, just a few days previous. Oh, yeah.

I guess that was it, wasn't it?
There doesn't seem to be any point in denying anything. She knows. I think if I didn't admit it, that would be a lot worse.
