AC 7217 - For distress of spirit.

AC 7217
...this state is signified by the burden laid on the sons of Israel by Pharaoh,
that they should search for themselves straw to make brick...
...they who are in a state near to despair are in internal anxiety,
and are then actually in shortness of breath.
In the external sense this condition is a compression of the breast,
and from this as it were a difficulty of breathing;
but in the internal sense it is anxiety on account of the deprivation
of the truth which is of faith, and of the good which is of charity,
and from this is a state near to despair.
