My ability to have intelligent conversation has been impaired by many years on psych meds. I often cannot think of a word I need or the best way to articulate my thoughts. I am also frequently sleepy (another med side effect, or an insomnia issue) - which also affects my language skills. I don't socialize very much because doing so takes an immense amount of energy. I'm a really good listener, though - listening is a lot easier for me than making conversation is.
