Hi Cally, everyone above gave great advice. Martin towards the end of treatment went quiet. Didn't moan or anything (which was worrying, he always moans about something), but before tbat he went through a mean phase too. I could keep him fed and watered and make surei looked after him and took him to his treatments, put him on the nebulizer. But I did really know how to deal with what was going on in his mind. I think he should have seen a councillor, to vent some fears and anger. Even Martin now says he should have done then. Your bother might halso be having trouble dealing with everything and is taking it out on the closest people to him. Maybe you could suggest talking to someone, he'll probably say no to start with but suggest again. It might help. Good luck.
