Have to say that's a completely bizarre time to offer someone time with the psych - don't you think?
You've just come out of the house having won, lots of family, lots of screaming and cheering, the Davina interview, all the press stuff.....and then you sit down and immediately have to try and make sense of it, before going back off into the whirl.
IMO Endemol should be offering the psych session a couple of days or a week after the leaving night, so that there's a bit of time to reflect on things (if people do in that first week.) And it should be compulsory as well.
As for meeting journalists unprepared.....well, seeing as I was one for eight years (not a national one I hasten to add, a quite friendly local one, lol) I can see how meeting all the hacks could be like being thrown to the lions.....
(not all journalists are like that though

)
