A UEA student warned a therapist they were "stock-piling" medication less than a fortnight before dying of an overdose, an inquest has heard.
Kasey Challenger, who studied psychology at the University of East Anglia, died at a halls of residence on campus in April last year.
An inquest into the death is being held this week and is scheduled to last three days.
During the first day of the hearing, the court heard Kasey - who used they/them pronouns - had recently returned to their studies having taken a period of leave due to mental ill health.
The student had been receiving several forms of support, including dialectical behaviour therapy (DBT) - a type of psychotherapy - from the Norfolk and Suffolk Foundation Trust and mental health mentoring at the university.
However, the 21-year-old continued to struggle with anxiety - with both the university and mental health services aware of the student's difficulties.
The court heard that on one occasion, Kasey had disclosed to university staff that they had "stock-piled" medication, resulting in security staff confiscating 140 packets.
But on April 4, nine days before the death, they made the same admission to therapist Richard Wink and it was not escalated to either their care co-ordinator or UEA welfare staff.
Asked why he had not taken this measure Mr Wink said he did not think it was needed at the time.
He said: "My assumption was that the plans we had in place for Kasey were quite robust because of the process they had managed."
Kasey, who lived in Dereham when off campus, died on April 13, 2023.
At the start of the hearing, Kasey's mother described their love of writing, poetry, music and creativity.
She said: "Kasey always loved making people laugh and if their family and friends being happy made them happy."
The inquest continues.
