Help, ASAP!

My ipod five's screen isnt working, the "slide to unlock.." thing keeps shimmering but it seems frozen, my top button works for turning the screen off and on, but my home button is completely broken, so im not able to reboot it by holding it down and the sleep/wake button down. For some reason only the Assistive touch thing works but im not able to do anything with it!! help me please!!
