The oil warning light is for oil pressure, not level. Serious engine damage can occur in a few seconds when the pressure is low, but it sounds like you already have major engine problems. Given the multiple symptoms it sounds like it started with a leaking cylinder head gasket and now coolant has gotten into the oil. That will melt the soft engine bearings which will lead to low oil pressure and further wear. I'd start by having your mechanic perform a chemical test at the radiator to verify the head gasket is leaking. If it is not, diagnose the cause of the overheating first.
