Slurring your words all of a sudden is not a good sign - you are probably have a TIA (transient ischemic attact or a stroke) - you really should be seen by the emergency department because you might need some medication such as TPA. And yes, you could have a broken neck and not know about it - again - this could be an "unstable" fracture - and I HIGHLY recommend you getting seen. Take care.
