Sounds like Depression to me, similar to Trescothick. Stress is usually short from for Depression in these instances. In which case, nothing else matters. That’s almost literally what depression is-life is barren and joyless and grey no matter where you are or what you do when its at its worst. It's an emotional and philosophical cancer. Wish him the very best.
I’m not sure the Aussies will have a go at this either. They’re pretty forward thinking on the mental health front, especially amongst males, it’s a big thing there. And I don’t recall them ever having a go in this instance. They’re vicious in the moment but I don’t think they would go after something like this, most of them are decent human beings when not playing sport.
