Victorians have a bad reputation for being supposedly stuck-up hypocrites who would conceal their feelings because they were too dishonest to talk frankly about what bothered them. They did, however, have a point. I noticed that when you keep talking about unpleasant things, you start feeling worse instead of better.
How many times did we all hear that we should never suppress our emotions and that if we have problems, the best thing to do is to share them with others? It works in some situations, but dwelling too much on the negativity only creates more of it. In the times past, people were taught to minimise their problems, to talk lightly of them and to concentrate on the pleasant things in life.
If you feel upset about certain things it's better to avoid discussing them. It may be politics or religion or family troubles or health problems or anything which makes you feel uncomfortable. If reading newspapers or watching the news makes your blood pressure rise, quit doing it! Life is too short to be wasted on worrying about things you can't change.
