a adult cartoon character exhibiting symptoms of fatigue such as tiredness, the person should be sat upright on a sofa with head resting on one hand

A vibrant, adult animated character slumped on a plush, oversized sofa, exhibiting clear signs of exhaustion. Their eyes are half-closed with dark circles underneath, and their posture is slouched. The character's elbow rests on the sofa's arm, with their head heavily supported by one hand. Their other arm lies limp across their lap. The room around them has a soft, warm lighting that emphasizes the character's weary expression. Include subtle details like a wrinkled shirt, tousled hair, and perhaps a discarded coffee mug on a nearby table to enhance the feeling of fatigue.
