Infinite Horrors? But I'm Mentally Ill

Lin Zao was doing morning exercises at a psychiatric hospital when she was taken to a strange place. There were creepy doctors and terrifying patients. Everyone else was so scared their legs were shaking. Lin Zao: "Have I been sent to the countryside for an internship?" In this world called Paradise, death lurked everywhere. But that was all right. Lin Zao had arrived, and a real lunatic was here. Physical therapy in her left hand, psychological counseling in her right. Either get beaten to a pulp or get cured. While everyone else struggled to survive in an infinite-loop world, Lin Zao recuperated in one. "How can you be back to normal?!" Then, one day, Lin Zao regained her sanity completely, and with it, she lost all the powerful skills she'd had as a lunatic. Everyone around her started blaming her. Lin Zao smashed a statue with one punch. "I'm the strongest whether I'm a lunatic or not."
