This book is a real-life experiment involving two young people suffering from post-traumatic stress disorder living in a precarious neighborhood in the city of Brazzaville in the Republic of Congo. This experience concerns a young girl and a boy, and takes place between February 2020 and March 2021. It includes case studies, psychological treatment and post-therapy care. It also looks at the environment, which is a precipitating factor for the local population in the onset of certain mental disorders, including neurosis. We have used psychological and geographical approaches for a better analysis.
