The paper describes the existential analytical model within which the content of suffering is denoted and structured. The model shows that we suffer from when we suffer. Suffering is diverse in its «how» and «why.» The author highlights the features of various forms of suffering in accordance with their classification in the existential-analytical anthropology and reveals the essence of suffering. Within the framework of existential analysis there is an assumption that experience is perceived as fulfilling with suffering when the fundamental structures of existence are threatened or damaged, and the features of the contents of these structures are considered. Significant attention is paid to the ratio of human suffering and the loss of human sense of life, what is behind the feeling of senselessness of suffering. Suffering and pain fully or partly represent a threat to our very life and throw into question human lust for life. To avoid this, it is necessary to appeal to the vast opportunities of a person, and drawing strength from its sources to meet adequately the destructive factors and the abyss of existence. 

The paper considers the issue of activity which enables stepwise treatment of suffering. The model of stepwise coping with suffering is proposed. It helps to overcome the stagnation in the condition of suffering and returns to the world and life. Practical steps are suggested. These steps are applicable for all forms of suffering. They lay the basis for gaining inner peace. So we can target our efforts over the suffering and prevent the occurrence of mental illness (e.g., depression, hysteria, addiction, PTSD, etc.).
