Such a psychological phenomenon as obsessive thoughts or obsessive-compulsive syndrome is not officially considered a serious mental disorder, but, despite this, it can significantly darken the life of a person affected by this ailment.
In order to better understand the essence of the problem, one can imagine that the human brain is a kind of biological computer that exercises control over the physiological, mental and biological processes that occur in the human body. The slightest malfunction of this computer can lead to serious consequences. The appearance of obsessive thoughts is just the same and is such a consequence.
Obsessive-compulsive disorder manifests itself in the form of mental chewing gum, i.e. thoughts of the same content that a person holds in his head for a long time and cannot get rid of it. Usually people describe this state as the need to come to a logical conclusion of the thought process, in other words, they simply are not able to let go of this thought, switch to something else. Constantly thinking about the same takes a huge amount of vitality, a person cannot concentrate on work, feels tired, apathy and even depression.
It has not yet been precisely established, as a result of which this ailment appears, but it can be assumed that stress, overwork, the inability to stop and put your thoughts in order becomes the main impetus for the disease. Gradually, problems accumulate in the mind, postponed "until tomorrow", which ultimately leads to the appearance of obsessive thoughts.
In order to get rid of this problem, you need to understand that obsessive thoughts are directly related to emotions. Any emotional outburst of great power triggers a chain of repeated mental reactions. You need to learn how to separate your thoughts from feelings and emotions.
A good exercise that helps in this situation is awareness. The essence of this exercise is to shift the focus of attention from thoughts to the current reality, to allow your thoughts to flow freely and independently against the background of everyday activities. The most difficult thing is to stop paying a lot of attention to your thoughts, but success, as you know, comes with practice.
If this problem causes great discomfort, you should immediately seek help from a specialist who will conduct the necessary analysis and prescribe the appropriate treatment, possibly containing effective drugs.
