I try to be in the moment with my T and try to remember everything that was said. Then I go home and process. Normally, I wind up remembering like 1 bad/unpleasant thing that happened and I dwell on it

But my T knows I do this, so it doesn't surprise her when I come to the next session overreacting to one thing (which is usually a misunderstanding).
As for SAT scores...I never took the SAT. But test scores do NOT show an accurate level of intelligence. So don't judge yourself too harshly on that. We each have intellectual strengths in different areas. My fiance is an idiot (

) in most things except when it comes to IT. My intelligence lies soley in logic, but I don't excel in any specific area otherwise.
And about following or not "rules". I'm not quiet so sure why that bothers you. I tend to follow "rules" a lot, but I also don't (there are too many things to be considered "rules"). I don't think it's a bad thing unless you're harming yourself or others. My T follows her professional "rules" to a t. But she's also admitted that she has road rage and would jay-walk. None of us are perfect.
I hope you feel better
