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 taking place in the human body. The slightest malfunction of this computer can lead to serious consequences. The appearance of obsessive thoughts is just such a consequence.
Obsessive-compulsive disorder manifests itself in the form of mental gum, i.e. thoughts of the same content, which a person keeps in his head for a long time and cannot get rid of it. Usually people describe this state as the need to come to the logical conclusion of the thought process, in other words, they are simply unable to let go of this thought, switch to something else. Constant thinking about the same thing takes up a huge amount of vitality, a person cannot concentrate on work, feels fatigue, 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 the main impetus to the disease is stress, overwork, the inability to stop and put your thoughts in order. 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 strength triggers a chain of repetitive mental reactions. You need to learn to separate your thoughts from feelings and emotions.
A good exercise in this situation is mindfulness. 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 hardest part is to stop giving your thoughts a lot of attention, but success, as you know, comes with practice.
If this problem causes great discomfort, you must immediately seek help from a specialist who will conduct the necessary analysis and prescribe the appropriate treatment, possibly containing effective drugs.
