Thanks for reply ladies.

Yes, DD1 does suffer from anxiety. Last year she used to complain of tummy pain a lot, to the point where we took her to a paed. He could find no medical reason for the pains, so put it down to anxiety. The tummy pains disappeared quite quickly once she had to go through getting blood taken for tests.

Sorry just realised I am too tired for a good reply. Will come back to this.
