I think you misread that statement. When he said he "reached his limit as a Shinigami" he wasn't saying he was exhausted, he was saying "I've become as powerful as I can as a Shinigami, but it's okay, because I'm about to evolve into my next form." He was taking Isshin's statement and throwing it back in his face.
