Anxiety is an integral part of human existence, a primitive survival mechanism that is activated in times of challenge. However, when it transforms from an occasional reaction into persistent mental tension, it has a decisive impact on daily life, functionality, and quality of life. In this book, psychologist and psychotherapist Georgios Konstantinos Ioannidis approaches the phenomenon of anxiety with scientific rigor and humanistic sensitivity. He examines its causes, manifestations, and implications in depth, analyzing both its theoretical and practical dimensions. From the biological basis of anxiety to its contemporary forms, and from the psychotherapeutic approach to self-help techniques, this work offers a valuable tool for understanding and personal empowerment. Written in clear language, it accompanies the reader on a journey of meaningful awareness, acceptance, and practical management of anxiety. It is aimed at those who experience anxiety in their lives, as well as mental health professionals, parents, educators, business executives, and anyone interested in deepening their understanding of this multidimensional psychological experience. A book that aims to offer a starting point for those who choose to turn, with knowledge and courage, toward a meaningful understanding of themselves.
