Language, thinking, and intelligence
Mz: Temple Grandin thinks in pictures.  She has written several books, including a book called "Thinking in Pictures".  You might find that helpful.  You might also try reading illustrated works, like webcomics, to help bridge the gap.  You could also pick up "The Cartoon Guides..." by Larry Gonick.  They aren't at all watered down.  My oldest son thinks in pictures and had trouble learning to speak but he is quite intelligent and, these days, articulate.  These are things that helped him.Good luck.
