The trust said the introduction of easier access through NHS 111 and increased publicity has led to a significant rise in calls.
Mr Ruddock attributed the increase to a range of influences, adding: “I think today’s world is a very pressured world.
“Younger people have a lot of social media type pressures, a lot of work pressures – trying to find jobs – then there’s the cost of living crisis.
“It makes people feel much more anxious, preys on their mind, preys on their mental health.”
Earlier this year, the charity said nearly 160,000 calls in 2024 related to concerns about finance or unemployment.
It was the third consecutive year the number of calls had risen.
Mr Ruddock, who has volunteered for seven years, said local people are not immune from these pressures.
“While Surrey is seen as an affluent county, there are pockets of deprivation, pockets of areas where people are struggling with their mental health,” he said.
Alongside the helpline, the trust also runs five Safe Haven drop-in centres – in Epsom, Guildford, Redhill, Woking and Aldershot – for adults struggling with their mental health.
Chief medical officer Dr Emma Whicher said these services are here to offer everyone “compassionate, expert care when it is needed”.
