Chocolate Teapot

What am I a chocolate teapot?
An empty sentence without a dot?
 
I melt when you say “hi”
And bleed after a final goodbye.
 
I never imagined you would leave
Not caring when my heart you deceive.  
 
I didn’t expect I was so useless.  
I didn’t exist to you I was worthless.
 
A dark shadow that one single night  
A mirage you laughed at in spite.
 
To be used then discarded
I thought I was loved or regarded.
 
I was wrong.
And this is my song.
 
For those of you who think you have found
Love. It’s just a sound in an empty background
