In the west there has been a prevalent view that crying is 'good for you, a cathartic release. However just because a viewpoint is widely held doesn't mean it is correct.
I am in no way a psychoanalyst, but have been trained in therapy and my background doesn't value 'letting it all out' over and above ' holding it all in'. Best is what ever floats your boat, suits you.
If you think of crying as just a means of communication, it helps ( I think) to make sense of why sometimes it seem right and appropriate and at other times just isn't the medium to use. Like smiling and laughing is possible when you are grief stricken or anxious or in another emotional state that doesn't immediately seem a fun time.
A friend recently told me about her inability to cry about her diagnosis of cancer and she is a cancer counsellor so is used to her clients weeping buckets, but it just wasn't the right response for her, which surprised her.
Me at the moment I start crying at the least and often no provocation - its not helping, its not healing its just damned irritating.
