The dynamic pace of life often doesn't allow us to dedicate more time to our emotions, nor to approach them in the right way to fully experience them. As a result, the emotions we feel, whether unpleasant or pleasant, are sometimes only superficially noticed without us making an effort to understand and associate them with the appropriate psychological state. Nausea, apart from physical stimuli, is often caused by negative psychological states of an individual, which then manifest through vomiting. The central focus of this work, emotional nausea, concentrates on the main character of the novel Antoine Roquentin and his psychological state both in a narrower and broader sense. From this, a very clear psychological picture emerges, revealing his own dissatisfaction and inability to adapt to life's routine. The paper will also draw a parallel between Gregor Samsa, Meursault, and Antoine Roquentin to more easily connect emotional reactions and the sense of absurdity. The most important goal is to delve into the core of the main character's psychological consciousness, his environment, and relationships with others to understand the main drivers of emotional and physical reactions.
