Kerrie, milky oil and low coolant likely means a failed head gasket. If this isn't something you're able to diagnose, and you were able to drive the car a mile home. You should be able to top it off with oil and coolant sufficiently to drive to a nearby mechanic. Depending on how bad it is, bring extra coolant and keep an eye on the engine temperature. If the engine gets hotter than normal on the way to the mechanic, pull over and add more coolant, waiting for the engine to cool down again if necessary.
