Mental overload often occurs when stress accumulates and your brain has been handling too many responsibilities for too long. Even small choices can feel exhausting because decision-making requires mental energy. When emotional pressure, lack of rest, or anxiety is present, the mind struggles to prioritise efficiently. Simplifying routines, reducing unnecessary choices, and allowing yourself breaks can help ease the burden. Writing tasks down and tackling them one at a time also restores clarity. If decision fatigue continues, a mental health professional can help identify underlying stressors and improve coping strategies.
