Now I am a lake...

Limbo :

1) (in the Roman Catholic religion) a place which is neither heaven nor hell where the souls of those who have not done evil may go after death, even though they were not Christians during their life
2) a state of uncertainity : I am in limbo, waiting to know whether or not I've got the job.

Purgatory :

1) (especially according to the Roman Catholic religion) a state or place in which the soul of a dead person must be made pure by suffering for wrong-doing on Earth, until it is fit to enter heaven
2) (often humor) a place, state or time of great suffering: It's purgatory listening to Tim's attempts to play the guitar.
