Have you ever?

The feeling of how you're always wanting something so badly, but it doesnt turn out ur way, sucks. Preferable as much, I wouldn't want anything. But as humans, we tend to ask. And when we ask, God gives it. And when we got it, we're always never satisfied.
We can't correct human mistakes, never. From what I'm experiencing myself, habits die hard. We tend to cause more repulsion than any explosions known to man kind. But, what happened when one turn scared, to let out his feelings? We can only open our big brown eyes, and let things passes by. It always seems easy to let it out. but not anymore when you've been in a situation where letting it out, was a mistake u made, pointed out by that someone.
So what can I do? Sit down..and hope, where all hopes have failed.
