Taunton: Somerset's newly-appointed captain Marcus Trescothick has revealed that he is unsure whether he will travel abroad again with his club after his aborted trip to India for Champions League Twenty20.

In an interview to BBC Sport, the former England  opener has said that a recurrence of his stress-related illness during the Airtel Champions League Twenty20, forced him to return home

But what if his team qualifies again in 2010? "Every case has to be treated individually. The problem comes when trying to focus on scoring the runs that I need to justify my position in the team."

The left-handed opener admits that the touring issue continues to trouble him. "I think that's got to be really looked at all the time and that's probably the area where a wise man would tell me not to do it anymore, I think," he said

The 33-year-old quit international cricket in 2008 because of anxiety attacks which he has suffered from since he was a child. He opened his heart out in a special programme on depression in sport. "I can't say yes or no (if I will compete next year) because I'm a professional sportsman and there's always that eagerness to go, right, I want to keep playing, I want to do something more, I want to show people across the world that I'm still what I used to be," added Trescothick.

"But at some point I've got to say there's no point me doing this because it's just no fun for me, the stress and strain for the family and the reward is not great enough to go through all of that."

The move to tour India for CLT20 is seen as a step forward from the time he thought about harming himself to prove he had a problem. "I considered hurting myself just to show people how much pain I was in," he said. "If you've got a broken leg you've got a cast on your leg, people can see you've got a problem but when you've got mental problems there is nothing evident to people to show you need help."

Trescothick was first affected by his illness on England's tour of India in 2005-06 and was then forced out of the 2006-07 Ashes tour leading to his international retirement.

Trescothick is just one of several top-level sportsmen to have suffered from a form of depression. Former boxer Frank Bruno, ex-Celtic player Neil Lennon and legendary All Black John Kirwan all battled with the illness and talk about the the myths and misconceptions that still surround mental illness.
