Sometimes I leave a session and can't remember a single stinkin' thing he said. That is really is more common than you may realize.

Rather than worry about what you don't remember, focus on what you do remember, and you remember A LOT. You really do. I'm really impressed at your recall because you've had many sessions where you remembered only what you THOUGHT your T was thinking and nothing of what she actually said. This is a VAST improvement. Good work.
