In my experience, the person that has difficulty in expressing feelings with words either doesn't know a great deal of words or has troubles with admitting to being weak and vulnerable which is, on some level, what we all are.

The literary history of the English language has had every possible emotion conveyed into words and it's flexibility means that the same can be done again and again. What can possibly so hard about articulating the way you feel, even in single-syllable words? The trouble is, our basic instinct to cover up our weaknesses with fake strength always seems to make the simple things like this more complicated than they are. How is language to blame for the individual's inability to put them together or making them sound sincere?

ideath says: "Two quotes for you from Lawrence Durrell 's Mountolive : 'Lovers can find nothing to say to each other that has not been said and unsaid a thousand times over. Kisses were invented to translate such nothings into wounds.' and 'The richest of human experiences is also the most limited in its ranges of expression. Words kill love as they kill everything else.'"
