a feeling of sadness and hopelessness
a long period of seriously reduced business activity and high unemployment
a part of a surface lower than the other parts
an area where the pressure of the air is low in the ground
"a low moved in over night bringing sleet and snow"
"he left the impression of his fingers in the soft mud"
"depression of the space bar on the typewriter"
In a state of deep depression, overmastered by those distasteful miserable memories.
