Perhaps, every person from time to time felt as if "doused with slops." But one cannot only blame others for this, because a person often voluntarily "delves" into negative information: cataclysms, earthquakes, crimes. Some directly relish this information, repeating it many times a day.
However, complete avoidance of such situations and people, as a rule, does not bring the desired result. You need to learn how to correctly prioritize, perceiving only important information for yourself, and treat the rest as given. First of all, you need to recognize that the world is full of negative energy, filled with "bad" people, wrong actions from your point of view. Denial of this fact will only lead to life in an illusory world, the destruction of which will lead to a breakdown in human thinking.
In this regard, the most valuable is the ability not to hide, but to cope with the surging negativity. To do this, define a circle of people among your environment, from which you do not benefit. If you need to communicate with them, for example at work, mentally imagine a brick wall. Then all the negativity emanating from the person will penetrate into this brickwork and remain in it, without reaching you.
There is another way like this. To do this, imagine a mirror between you and the unwanted interlocutor. In this case, his negative emotions will reflect on him without touching you.
Sometimes you can "bark", that is, openly express your dissatisfaction with the annoying boring interlocutor. The main thing is to do it tactfully, without going beyond the bounds of decency.
