Nobody here can help you find your phone. Apple does NOT track devices.
Use Find my iPhone, but it must have been enabled BEFORE you lost the phone. Login to iCloud with your Apple ID.
Call the police and change your passwords.

You must sign iCloud in and turn on Location.
Your idevice also must be turned on and with internet connection. Otherwise, Find My iPhone will just show you the last location that has been updated.
Hope it helps
