Summarizing the historical background and characteristics of the present, it should be noted that they are significantly different from the characteristics of the world where past generations lived, which undoubtedly poses new challenges for the human ability to withstand the growing pressure of stress factors. The article considers the problems of psychological resilience and fragility in terms of Existential-analytical psychotherapy of V. Frankl and A. Langle, analyzes the historical context of the present-day Ukraine, external and internal characteristics of the modern (...) world, identifies the role of personality in overcoming negative stress influences, proposes a therapeutic model of optimization of psychological resilience in the context of four fundamental existential motivations. The analysis of recent research indicates that the most important resource of psychological resilience lies on the personal level. Using the Existential-Analytical concept of personality structure (Dr. A. Leangle), the article analyzes the preconditions of the emergence of a threat to loss of integrity in each of the four fundamental existential dimensions. On the other hand, stability is ensured by the full realization of being in the following existential dimensions: relations with the world, which requires space, protection, and support; a relationship with life, a deep feeling that life is good; interconnection with oneself, awareness and respect for their own authenticity and uniqueness, which requires honest and attentive attitudes, recognition of their own values; relationships with the meaning -- awareness of the value and potential of one’s own live, the search for the ways to realize its meaningful integrity.
