Never enough words

There are never enough words to express gratitude, love, heartache etc... why is that I wonder. I wonder about this because there are so many people I am thankful for yet I never have enough words or emotions to thank them. I always feel that I need to do something in return but never seem to know the right things to do. I am not crafty, I don't sew, knit, crochet, draw etc.. I bake occasionally, I write. I am a very grateful person for people who have done things for me, for people who have been there for me in my darkest hours. I just can't seem to express how amazing I feel about some of these people. A few of them I have never even met personally they are just online. So I ask myself all the time.... what can one do to show appreciation? I'm a shoulder to cry on, an ear to listen, a tear to cry with, a smile, confidence to boost you,  but is that enough?  There is never enough words or actions when you are truly grateful for people. I'm hoping one day when I am face to face with some of these people I admire and cherish as friends that my hug will more then enough be sincere to show them that they mean the world to me and Thank you.
