I didn't have problems with dyslexia, but early in recovery I had problems with some verbal word finding, and problems with short term memory caused me to repeat myself often. Occupational and speech therapy was helpful in resolving this.

I’m not a doctor or psychologist but with your history of dyslexia it may just be resurfacing when you feel stressed. Slow meditative breathing may help calm this. Otherwise it sounds as if you have recovered pretty well. Best to you.
