I will try to help you.  I am looking at my iPhone right now.  Click on your Facebook app.  When it opens scroll all the way down until you see settings.  Click on the settings.  When that opens up click on the first tab "General" and all of your information will be showing.  I assume that the username would be your email address that you sign in with.  Good luck!
