England batsman Jonathan Trott has been told the door is always open for advice and support by Marcus Trescothick.
Trott is to take a second break from professional cricket because of his stress-related illness.
A joint statement by the 32-year-old's employers at the England and Wales Cricket Board and Warwickshire on Friday confirmed that he will stop playing with immediate effect.
Trott, who had to leave England's Ashes tour after the first Test in Brisbane last November for the same reason, made a shortlived comeback at the start of this season.
The Warwickshire player has attracted criticism in some quarters for his handling of the issue but Trescothick, whose battle with depression saw him pull out of England's 2006-07 Ashes tour, is better placed to understand what his peer is going through.
The Somerset captain said: "I've spoken to him on a few occasions just to try and help, as someone who has been through exactly the same situation, coming back from Australia. I can understand it. I know how it all works.
"Whether we cross paths and talk a few more times over the course of the year and during games, or wherever it may be, then great.
"I can help him and we can also help each other, see how it goes and he works it all out."
Criticism of Trott centred mainly on his use of words such as "nutcase" and "crazy" in an interview following his return from Australia, which led to questions over whether the 'stress-related illness' was in fact a mental health issue or simply a player struggling under pressure and poor form.
Trescothick understands the backlash but is eager to emphasise that only Trott knows what he is going through.
"Look, I understand. I saw the interview and I've been in touch with Jonathan, so I can't say a great deal on it," the 38-year-old said.
"I didn't have a problem with what he said. People picked up on words and it was taken at the wrong time and the wrong moment. But people are always going to pick up on things that you say and challenge what you say in that environment because that's their job.
"We have to allow him the fact that he's the one going through it, he's going through tough times and he has to work it out himself.
"We have to take what he says, understand it and give him that opportunity to make it right."
