My England seem to be gettings worst

Perhaps I'm being a little too self-conscious, but I've been noticing that when I talk, I'm starting to stammer and even have trouble pronouncing long words like 'totalitarian' and 'inexplicable'. I don't know when this started but it does seem like my grasp of the English language seems to be slipping, at least when it comes to speaking.Could it be that I might also share a little bit of dyslexia that both my brothers have? Perhaps it's a sign that I should just get out more and start talking to people rather than being an introvert and staying at home.
