I draw too! and write poems and what not. and it's not so much as finding the right word but more the meaning behind them. then again word choice came naturally to me eh. none-the-less I hope you find what you are searching for.

You should do it, you will feel more confident and be able to express your feelings like that ! I think that some people in this world are into art expression, they can't express ourselves with words by conversation
