What can be revealed from the other side of fear?

If it is impossible to get rid of fear at all, there are subjects or situations, causing fear that can be eliminated, replaced, or dispensed without them. For example, with an evil wife (husband) who regularly and gruelingly causes fear, you can divorce, replacing her with another, or you can never marry at all. You can do the same with a picky and nasty boss.
True, the other subjects producing fear will not go anywhere.
Besides, there are false, or invented, fears of non-existent dangers. Here you can fight them. Although directly to the true fear caused by the real threat, they have no relation.
But, alas, a lot of subjects or situations that cause or giving birth to fear, such as the opponent's hatred, diseases, death, cannot be eliminated, replaced, or circumvented, but it is possible to try to debar oneself somewhat from them, for example, to stop thinking about them, although the very threat, the precursor of which is fear, does not disappear anywhere from this.
In addition, sometimes fear in relation to certain phenomena, especially social ones, has such a positive meaning that it needs to be supported, not fought against. Examples of this are shown below.
