An engineer who killed himself wrote in a suicide note that "the pressure of work has turned my mind into a ticking time bomb", an inquest has heard.
Wayne Williams had been working as an engineer
Cardiff Coroner's Court heard how 28-year-old Wayne Williams hanged himself after a party to mark the end of a year-long contract in Singapore.
His body was found in his flat the next day along with two notes.
Coroner Mary Hassell recorded a verdict of suicide on the death of Mr Williams from Llantwit Major in south Wales.
The inquest heard how Mr Williams had been at a party celebrating the end of a successful year-long project working on oil tankers in Singapore.
His body was found the next day hanging from a bedroom door by a leather belt.
The court heard that two notes were found.
One note, addressed to his work colleagues, read: "Unfortunately the game has got the better of me - give my apologies to all the lads."
The other to his parents read: "I have been depressed for a while now - the pressure of work has turned my mind into a ticking time bomb."
The inquest heard how Mr Williams' friend Richie John said he had heard Mr Williams talk about suicide.
Mr John said in a statement: "Wayne said 'sometimes it would be better to just top yourself'.
"I thought he was joking and told him not to be so down.
"But about a week before people had noticed he wasn't being himself.
"He was normally happy-go-lucky and chatty but he became quiet and reserved."
Cardiff and Vale Coroner Mary Hassell told Mr Williams' family: "I'm sure it must be very shocking and difficult to understand why Wayne would take his own life.
"I wish I could tell you more - it is hard to understand why someone described as happy-go-lucky should choose to end their own life over pressure in work."
