You may be suffering from Major Depression with psychotic features given the symptoms you described.
Though symptoms may be similar with temporal lobe epilepsy, the probability is low given your good mental condition prior to your symptomatology.
I recommend consulting your physician for a thorough evaluation. You may benefit from tests that can rule out physical causes, medications and therapy for your condition
I am no doctor but that does not sound like epilepsy. It sounds like psychosis of some sort. You need to get a psychiatrict evaluation as soon as possible. You may have a physical condition that is bringing that on.
Drugs and alcohol can also cause temporary psychosis so if you are doing either of those you may want to stop and see if the symptoms go away.
