Just a feelings written on the sand !

with feelings of pain , my hands began write on the sand
built a castle with a lot of words , all the doors brings sadness
i'm only look of tears windows , how much is big this castle to built in my heart
or my feelings live in it , it's hurt when opens by pain keys
hide my smiling face , nothing deserve to hold sad feelings
nothing deserve to stay prisoner in this castle and there is a lot of things attrats happiness and repels sadness
i wrote it on the sand cuz i know , will mix with waves , spread with wind , gradually will
vanish cuz feelings of happiness still alive , so i make it habit to be HAPPY
