Hereof, how do I get my message icon back?
Open your App Drawer, find Messaging, long-press it, and drag it back to the homescreen.
Additionally, why did my message app disappeared? Go to System Settings/Apps/All, and scroll all the way to the bottom. Disabled apps are usually moved to the bottom of the list (except in Android 4.3, where there's a separate Disabled list to the right of All). Welcome to Android Central! You can't drag from the Settings>App Manager menu.
