The mental illness that corresponds to the symptoms you described, such as feeling stressed, experiencing heart palpitations, nervousness, and panic when in trouble, and responding with excessive details when questioned, could be Anxiety Disorder, particularly Generalized Anxiety Disorder (GAD).
Generalized Anxiety Disorder is characterized by excessive worry and anxiety about various aspects of life, including daily situations and potential future events. Individuals with GAD often experience physical symptoms such as heart palpitations, muscle tension, restlessness, and a feeling of being constantly on edge. They may also have difficulty controlling their worry, even when they recognize that their anxiety is excessive or unwarranted.
People with GAD may feel particularly stressed and panicked in situations where they perceive trouble or anticipate negative outcomes. They may overthink and ruminate about potential problems, leading to heightened anxiety and nervousness.
The tendency to respond with excessive details when questioned could be related to the heightened anxiety and the need to provide reassurance or clarity about the situation. This behavior might be an attempt to avoid potential negative consequences or to gain approval from others.
It's essential to note that a proper diagnosis can only be made by a qualified mental health professional after a thorough evaluation of the individual's symptoms, history, and overall functioning. If someone is experiencing these symptoms and it is affecting their daily life and well-being, it is crucial to encourage them to seek help from a mental health professional for an accurate diagnosis and appropriate treatment.
