LAKEWOOD, Colo. -

A woman who survived for days after crashing off a Colorado highway faces a long recovery.

Kristin Hopkins was in critical condition Wednesday, her 44th birthday, after doctors were forced to remove both of her feet.
    
Her flipped car was discovered Sunday by a husband and wife driving on U.S. Highway 285. They stopped after noticing some glare and notified authorities, never expecting the car's passenger to still be alive.
    
Investigators say Hopkins crashed sometime after she left work on April 27, the last time the single mother of four was seen before she was rescued.
    
Her parents and doctors were scheduled to talk about her recovery Wednesday, but St. Anthony's Hospital in suburban Denver canceled the press conference, saying the family wasn't ready to talk.
