Oh, how neat that you figured out the dyslexia/wrong/erase part! I had something similar with my need to always correct people's grammar/spelling. I suddenly figured out 10-15 years ago that, because my mother had aphasia as a result of her brain tumor operation, right when I was learning to talk, not speaking well meant the person was going to die (like my mother did)! So, I couldn't allow mistakes with words. Too, when I get excited or anxious and am talking, I get all mixed up and trip over my words bad, leave out key information and go blank, etc. It's been a great help working on it though, having a clue where it might have come from/formed at.
