Why Can'T I Be Happy?

Why can't I be happy when the world is at my door? I have all that I'll ever need. I couldn't ask for more. Then tell me why I'm empty. Why do I feel so low? I wonder what is wrong with me and if I'll ever know. My brain say's 'stop debating.. you over-think too much! ' But, my heart just screams and begs for things like time and things of such. The little things I'm needing. Just little, thoughtful things, not the fancy houses or the cars and diamond rings. Maybe I'm just greedy. I should be satisfied. So I will do just like I should. My feelings I will hide. Perhaps I am too different. I feel my heart can't show. I fear I'll always be this way... deep in sorrow when no one knows.
