What I could this possibly be? I just woke up this morning and my voice is gone and I have an earache with a serious cough.

Ppssibly laryngitis. If it were me I would go see a doctor, and in the meantime stop drinking milk or eating anything with sugar in it: this would likely help heal your throat, since sugars and milk actually contribute to growing MORE of the germs that cause illnesses, sore throats, etc. Get some vitamin A&D about 5000 IU, and Natural C with Bioflavonoids 500mg. Eat a lot of organic green fresh veggies, orange veggies, veg juices, veg and clear soups to help strengthen the body and fight off /prevent illness.
