Anthony,
While reading your post I found myself wondering if you thought there was a difference between men and woman and how they view and use sympathy and empathy?
Women tend to be more sympathetic than men, genetically, as women are more emotional than men, genetically.
Saying that, sympathy is irrelevant to men or women after the initial event itself. It doesn't help process the negative emotion, it only helps keep you within the negative emotion, which is an abuse cycle.
Where not talking about a marital breakdown or such here, I am only referring to trauma that has caused PTSD, and the person has PTSD. If you have PTSD, then sympathy is no longer a valid emotion because it is destructive to PTSD mechanisms.
Sympathy in most roles only has a sustained time period, anything after that period the person still becomes stuck in a milder abuse cycle. It is like someone who holds onto the grieving of a loved one for years and years, ie. they are still grieving two years later, as a result, it has affected their life to a negative degree. If you grieve for two years, but still function, perform, socialise, etc, then that grieving is not negatively impacting your quality of life, which means highly likely, not impacting your health.
These are factors that must be associated at all times, however; PTSD is impacting you negatively already, so it rules out all other aspects. If you told me you have PTSD and have no impairment to social functioning, work, etc, then you don't have PTSD, because you don't meet the diagnostic criterion. This is why if the term PTSD is used, there is no assumption being made that negative impairment is present. You either have it, or you don't, and with PTSD, comes negative impairment within specific aspects of your life.
