Does it have any leaves left? If not I would suggest giving it a proper burial, once the top middle leaf is gone you are done. If it is dropping them from the bottom up and there are still one or two left, you may be okay, it may be in survival mode. When you have a plant with root rot, or that is clearly in distress/dying mode, you should cut the flowering spike to help the plant save it's energy for living. Do you have a recent pic of it?
