I've only ever really been asked in terms of current situation. You say you are "stable, no sui". If I understand correctly, you are referring to ideation (of active sort) and that you're not having it. The questions, in my experience, come in parts, with the asking of each subsequent question being based on the preceding answer. Ie., question one: Are you feeling sui? (Answer no, move on) if answer is yes, the second question: do you feel you might act on it? (Determining active or passive ideation). If answer is yes, question three: do you have a plan?

It would seem unusual to me if she went straight for question three. (I'm envisioning, "Good afternoon, come on in, do you have a plan?")

Mine always starts with, "So how have you been doing?" It only even goes to the other questions if my answer (or behavior, I suppose) indicates that they should be asked.

Thing is, I do have a plan. Have for years. Question is, where on the continuum of thought level is it? Is it a tidbit of random information (in brain simply because once thought cannot be un-thought)? Is it totally passive thought? Is it something I'm probably giving a bit too much thought to? Is it something I'm definitely thinking too much about? Right on up to it's taken over my thinking. These are very different things of course.

And yes, having explained that to her, my psych knows I could never in 100% honesty say I don't have a plan. But (for me) that in itself doesn't necessarily mean I'm in crisis. Her response is based on current thought level, not simply on account of its existence.

Does that make sense? Does that help you reality-check your paranoia? (If not, please say.)
