What would you do if an angel came down to you and revealed that you are in fact Satan?

Let’s say he reveals that you, Satan, had been banished to Earth by God and erased your memory, to live among humans for whatever reasons. To further compound this, he waves his hands and you grow 2 pairs of black, scorched feathery wings on your back, and also all your memories of your past existence as Satan suddenly return. How would you proceed from there on and how would your further existence in the world be characterised?
