You might be able to be diagnosed, but there’s no medication or cure. You can get extra time on tests if you’re younger.

You can Google dyslexic signs. I think last time I looked auditory processing anomalies and the retina or lens was oddly shaped in 95% of dyslexics. Dyslexic is also an umbrella term for a bunch of things so you’ll have to sort through to find your flavor.

Best fix is a good nights sleep. Also make sure you move closer to speech you want to comprehend and the people you interact with most enunciate and speak at a good volume (too many people speak poorly and could use 2 weeks of beginner theater classes)
