the truth is in the details

I often wonder if the trouble I have expressing emotions/feelings is due to the language I speak. There are only a finite number of words in the English language, and there are even fewer in my personal lexicon. Therefore, I left with only limited range of words to express ALL the things I feel. Instead I have to string words together to fill in the gaps, but I get the sense that it isn't always good enough. I can't think of any examples off the top of my head, but I bet you can.
