Toejam - understanding where your therapy sessions are going and finding out who you are is great. Being on the perfectionist side of things isn't all bad, you know. Tempered with a little give when it is appropriate, perfectionists tend to be great employees and good at whatever they do.
Good for you for asking for what you want out of your time in therapy. If your mind likes to categorize and understand things, it must feel like a relief to have some insight. I like your style!
