A friend of mine had that happen with a text I had sent a long time ago... after a few weeks thinking it was something with his phone I was looking around at my settings, and saw the text message in the Outbox folder. If you go into your email folder and hit the down arrow for Inbox, you can see the area (and different folders) under Text Messages.

If that doesn't work, let me know. I have a jar of peanut butter.
