Listening to the "talking heads" discussing Murray's woes, and several times, by several of them, it has been referred to as a "mental breakdown" while he was on court. Serious words. I'm assuming there are no further problems with his gf?
We don't know about Kim, but, although Andy had a worrying mental aberration on court, this most definitely is not the same as a mental breakdown. Had the latter been the case, he would have been unable to function. As it was he managed to get through the interview, go back to his hotel and return to the UK. I do wish people who haven't got the experience would stop throwing these sort of expressions out.
