Where has everyone gone?

This 23 year old girl wakes up from a 7 month coma, only to find everyone gone.
"Where am I?" , "Where is everyone?", "Whats going on?" , is all she can think, until she turns around to see she is in a hospital - in section 3, a coma unit. She has no idea who she is or how she got here, but is desperate to find out. Except she has no clue where to start... or does she?
