He seems like a guy who shruggs them off real fast. Just check the run he's been on since the 2011 US Open semi-final loss. A loss that would tear lots of players apart. Since then Fed has lost only 9 matches and won 75+ Even back in the day in 2008/2009 when he wasn't used to that many heartbreakers, he still recovered well. After losing the 2008 Wimbledon final he did win an Olympic gold medal and the very next major (the US Open). After losing the 2009 AO final he also went on to win the very next GS tournament and went on a 20+ match winning streak or something. After losing to Djokovic at the 2010 US Open having squandered 2 match points he barely lost before the final of any tournament that year and going into 2011 (Shanghai final, Paris SF having match points, wins in Basel, Stockholm, WTF, won Doha next year). Nadal on the other hand, while mentally tougher in actual matches, has never done well after heart breaking losses. 2009 FO, 2012 Wimbledon, most of 2011 after being beaten by Djokovic that many times.
