Pode ser que ao dissecar o teu significado palavra por palavra, analizando cuidadosamente os teus inumeros angulos e facetas, eu consiga perceber porque é que me consomes as entranhas. Até la, fico parada que nem um animal que se finge de morto, esperando que te aborreças de me habitar

Anxiety (also called solicitude) is a psychological and physiological state characterized by cognitive, somatic, emotional, and behavioral components. These components combine to create the painful feelings that we typically recognize as anger, fear, apprehension, or worry. Anxiety is often accompanied by physical sensations such as heart palpitations, nausea, chest pain, shortness of breath, stomach aches, or headache. The cognitive component entails expectation of a diffuse and certain danger. Somatically the body prepares the organism to deal with threat (known as an emergency reaction): blood pressure and heart rate are increased, sweating is increased, bloodflow to the major muscle groups is increased, and immune and digestive system functions are inhibited (the 'fight or flight' response). Externally, somatic signs of anxiety may include pale skin, sweating, trembling, and pupillary dilation. Emotionally, anxiety causes a sense of dread or panic and physically causes nausea, diarrhea, and chills. Behaviorally, both voluntary and involuntary behaviors may arise directed at escaping or avoiding the source of anxiety and often maladaptive, being most extreme in anxiety disorders. However, anxiety is not always pathological or maladaptive: it is a common emotion along with fear, anger, sadness, and happiness, and it has a very important function in relation to survival.
Neural circuitry involving the amygdala and hippocampus is thought to underlie anxiety. When confronted with unpleasant and potentially harmful stimuli such as foul odors or tastes, PET-scans show increased bloodflow in the amygdala. In these studies, the participants also reported moderate anxiety. This might indicate that anxiety is a protective mechanism designed to prevent the organism from engaging in potentially harmful behaviors.
