What Am I?

What kind of this feeling I have?
It's like a bomb,
Continues to explode.

What kind of emotion is this?
It's like a clicking clock,
Counting nonstop which hard to hold.

What kind of mind I do have?
It's like plain but dreamy,
Without an action.

What kind of self am I?
It's like moving but no path,
Going forward without a plan.

Then what kind of person am I?
It's like a full outside,
But continues to empty in inside.

What am I?
A hardworking person,
But the truth I'm just a total failure.
