Comfort ourselves with a journey (4)
I believe the answer is:
tour
'a journey' is the definition.
(tour is a kind of journey)
'comfort ourselves with' is the wordplay.
'with' says the answer is hidden in the clue.
'TOUR' can be found hidden inside 'comfort ourselves'.
(Other definitions for tour that I've seen before include "Journey to visit places of interest" , "Extended journey" , "Trip visiting several places" , "Pastoral people of East Africa" , "Entertainer's itinerary" .)
