Yates then stopped taking medication, mutilated herself, and read the Bible feverishly. She stopped feeding Mary. She became so incapacitated that she required immediate hospitalization. On April 1, 2001, she came under the care of Dr. Mohammed Saeed. She was treated and released. On May 3, 2001, she degenerated back into a "near catatonic" state, and filled the bathtub in the middle of the day; she would later confess to police that she had planned to drown the children that day, but had decided against doing it then. She was hospitalized the next day after a scheduled doctor visit; her psychiatrist determined she was probably suicidal, and had filled the tub to drown herself.
