Stress is often the cause of this getting bad. During non-stress times, you may do much better but at the first struggle, you get frustrated and up your stress level and crash. Your anxiety over the NPA has likely added to your stress levels recently.

My wife and I learned to make light of my struggles, especially since many times I would come up with words and such that were plain silly, if you looked at the struggle with a sense of humor.

A term for this mess up some of us have used is 'Brain fart.' Their are embarrassing and we can't believe they came out of us.

My best to you.
