Social Pain

I have just been reading an article from Brain-pickings (posted on Facebook) about the essential connectedness of humans. One point it makes is that what it calls "social pain" (i.e. the loss of a loved one or the failure of an endeavour) is felt in essentially the same way as physical pain, but we look upon it very differently. As they point out if we have a broken leg or something similar we are not told "to just get over it" . This is something that I must have understood intuitively, because I am disturbed by the present day attitude to grief.  Sorrow has become socially unacceptable. We are not allowed to mourn. We may mention our physical pains, but not our emotional ones. So many people I come across are taking anti-depressants. Surely it is natural to be unhappy sometimes. Life is not a perpetual bed of roses. Shouldn't we accept this fact instead of trying to run away from it.
