I understand how you felt.
It happened to me once before on Continental.

On return flight to home, my luggage didn't show up.
Next morning between 4AM-5AM, my home phone rung.
I couldn't pick up early enough before it was forwarded to voice mail system.
Then a few minutes later, I heard truck engine noise in front of my house, then heard door knocked. I slowly put my clothes, open the door - my luggage was sitting there.
The truck was about to leave, and the driver was waving to me, with smile.
I waved back with blank smile...
