Thanks for your replies guys;

Phil - that is helpful for me to know. I had a feeling that I shouldn't contradict what my friend says - as in her mind she is right.

Mandy - your comments make a lot of sense as well.

I got a text from her husband today saying that she was 'confused' and 'exahusted' and that things were getting better. I'm just glad she's moving out of the mania she's had for the last 3 days.

Cheers

Jess
