don't try to drive it anymore. it's an oil leak on the front (true front) side of the engine. possibly the front main seal, valve cover gasket, or a bad head gasket.
does it overheat, or duz the temp needle get above half?
sounds like u r losing oil, and that's y it's running slow due to increased friction on the bearings. the grinding noise is most likely from the thrust bearing having worn down. u'r probably real close to spinning a bearing if u haven't already. my reason for these suggestions, is the obvious neglect of the car.
