I'd say Robin. I mean, for the others, even though someone dear to them has died, they still had others (such as Luffy still having Ace and Garp when Sabo died, or Chopper having Kureha when Hiluluk croaked). Robin, however, lost absolutely everyone when Ohara was annihilated, and was alone and cannot trust anyone for 20 years. Well, Brook was alone for 47 years, so he may be an equal or worse.
