A trainee accountant died after falling to his death at Beachy Head.
Tributes have been paid to 22-year-old Alfie Ronan, whose body was found at the foot of cliffs on Monday July 16.
An inquest at Eastbourne this week heard the month before his death, Mr Ronan, who had a twin brother, had been taken to hospital in Aberystwyth after threatening to take his own life in Swansea.
He was allowed to leave the hospital by the Oxlea NHS Trust and after returning to his family home in Sidcup, travelled to Eastbourne by car.
His vehicle was picked up by automatic number plate recognition cameras and found in a car park at the beauty spot.
Mr Ronan’s body was recovered by the Eastbourne lifeboat after a search of the coastline by lifeboat crews, coastguard and Beachy Head chaplains.
He was described by his family as a happy inquisitive person who had a “great capacity for kindness”.
He enjoyed playing rugby and cycling, had run marathons and went to football and rugby matches with his twin brother George.
However, in recent months he had suffered with low moods and talked about suicide after a relationship with a work colleague failed.
Following Mr Ronan’s death, a review was held by health watchdogs and flaws in the system were recognised.
The investigating officer Karen Prior said Mr Ronan had been released with no further follow up by the trust and that lessons had to be learned.
A spokesperson for the trust said staff had been investigated, an action plan had been produced following the review and that more training was being provided.
