The problem here is you guys are comparing apples to oranges - psychological pain caused by a physical issue/impediment/tragedy and psychological pain caused by an emotional/mental tragedy. These two pains, are completely separate animals - which thus have two completely different effects on the mind.
Let's start out with psychological pain caused by a physical issue. For this, we shall assume that it was caused by an accident, one which could not have been prevented. This sort of thing is unavoidable (most of the time); and depending on when it happened in the lifetime of any given person, they probably have a reference to 'before' their accident happened. Say this person looses their legs and their sight in an explosion. So now he is unable to walk, and he's blind. He has to deal with the knowledge that he is different from everybody else around him, and since he is blind, he's unable to tell the reactions of others around him - to his physical limitation that is. That's one thing right there, a sort of uncertainty, a fear, an insecurity. Then he has to deal with his associations with his loved ones, where that fear probably isn't present, but there's still a sort of pain caused by the idea that he won't ever see the face of his loving daughter again, he won't be able to watch the stars with his wife gain, and so on. That is a horrific mental pain and suffering in and of itself, no? But he still has memories, and his family to comfort him, he still has solace, he can find peace and cope.
Now, onto the psychological pain caused by an emotional blow. This is a completely separate entity to the pain caused by a physical issue. For our example, let's use somebody who hasn't ever had a girlfriend, who's only ever been constantly rejected, who's been abandoned by his friends and cast out from his family. He has a sort of mental isolation, a pain that's caused by knowledge of the unknown, that he hasn't and might not ever know the loving touch of another, that his family and friends whom used to care for him, now won't even talk to him. He has nobody to turn to, and he's been let down time and time again. He no longer wants to find hope, to find peace, because he's petrified that he'll be left alone again, that he'll be rejected once more, and that all he had known has been ripped away once more. He ceases to find meaning in life, and slips into the nihil of hopelessness, and he doesn't see any point to it. He doesn't have a meaning, a purpose, any livelihood. Once that happens he's a husk of his former self, and that cannot be fixed either. For him, it isn't just a mere broken heart, it's the realization that all he's hoped for, all that he wanted, his meaning - purpose - his very existence! Has been denied to him; and thus ripped away. This, much like the pain caused by loss of ability to walk and see, cannot be fixed.
