I like the direction you went with the notion of deception. I can see that there is a lot of pain that many of us hide under fake smiles. Sometimes, it's almost as if it's an unspoken rule. If I may suggest anything - I would describe the pain a bit. Make it vivid and real - so that the pain can be felt by the reader, and it can be seen.

I think you would find this article helpful: Resolving Emotional Abstractions. It helps the good poetry become better ;)
