I have Fast Boot on so I cannot access bootloader and I do not have USB Debugging on.
PLEASE HELP ME I DO NOT KNOW WHAT TO DO.
of course you took nandroid backup before flashing new theme?
Hmm, maybe not...
since you have flashed a theme I presume you're unlocked with custom recovery.
Go into recovery (hold power button and volume down at the same time while phone is off) and just dirty flash the rom you are using and you should be ok.
