WHY SO BAD WITH WORDS?

I used to think why am i so bad with words? Like for some reason i couldn't select the right words for the on going discussion.Most of the time i would remain silent and stand bewildered not knowing what to say.At times i was unable to put my emotions into words and connect with the people around me.My head and my heart exploding from emotions but my lips sealed or even saying the opposite things. 

But now that i think of it.I believe every person tries to explain his feelings through words but some of them are good at it putting up to 70 or even 80 %  of what they feel into words but some are like me who barely can explain 10 or 20 % of his feelings.So i conclude "EVERY FEELING CAN NOT BE EXPLAINED THROUGH WORDS MAY BE UP TO A CERTAIN EXTENT BUT NOT COMPLETELY SOMETHING ALWAYS REMAINS DEEP INSIDE"
