Shell shock

I'm sorry, but this is just a whinge. Tonight, on the television news, there was a report about a young woman who was allegedly 'held up' at gun point and robbed. The reporter telling the story told how the young woman was left 'shell shocked' by the experience.
I am so tired of hearing people expressing the view that someone was 'shell shocked' - or that some small drama or other left them 'shell shocked'. Shouldn't the expression simply be 'shocked'? The term 'shell shocked' (as I understand it) originated from stories of poor soldiers in World War One, who were traumatised by being bombarded by gun fire, with 'shells' raining all about them, while they wondered when they might be next on the receiving end of a fatal bullet. Many soldiers who survived the awful atrocity of that war, reurned home utter wrecks, unable to work or cope with life in general.  I suppose that, today, we would refer to the condition as 'post traumatic stress disorder'. It is (and was) a very serious condition and those poor soldiers (and the memories of them) of 100 years ago, should surely still bear our respect, by not referring to every slightly shocking situation as causing people to suffer from 'shell shock'.
I mean...when you hear someone exclaiming that the cost of something left them 'quite shell shocked' it's a bit bizarre and quite frankly, wrong.
So, there's my whinge for today.
