Sadness

knock knock. whose there? sadness. sadness who? there's sadness inside of me It's so dark and empty inside I don't know what went wrong. I try to find happiness but it wont stick. I try to have some fun and hope it will be done. and as you see there's no smile no laughter no singing and every time it stings me. can you feel my saddness-? can you feel my pain?
