I struggle with this myself, frequently telling my T that his problem is that he just doesn't understand my unlimited capacity for screwing up. His response is always that we need to focus on getting me to recognize my perceived "screw ups" before they happen. I hate that he has an answer for everything.

At least see if you can try to take a little baby step to stop looking for ways that you are hard on yourself because you are being hard on yourself for being hard on yourself.
Give yourself a little pat on the back and tell yourself that maybe it's true that you are hard on yourself, but that's just the way it is right now. Breathe in. Breathe out. In that breath, it didn't matter, did it? One teeny weeny bit of progress right there. Good for you!
