ready to do anything regardless of danger
tried when all else has failed
in great need
extremely difficult and dangerous
"they prey on the hopes of the desperate"
"a despairing view of the world situation"
"the last despairing plea of the condemned criminal"
"a desperate cry for help"
"helpless and desperate--as if at the end of his tether"
"her desperate screams"
"a do-or-die conflict"
"a desperate criminal"
"taken hostage of desperate men"
"made a last desperate attempt to reach the climber"
"the desperate gallantry of our naval task forces marked the turning point in the Pacific war"
"they took heroic measures to save his life"
"felt a desperate urge to confess"
"a desperate need for recognition"
"a desperate illness"
"on all fronts the Allies were in a desperate situation due to lack of materiel"
"a dire emergency"
I am desperate of obtaining her.
