I am convinced that every little twinge/ache I have is a symptom of something more serious. Everytime one of the kids has a pain I'm the same. DD (2.5) is very tird at the moment - but fine in herself & I've convinced myself that she has soemthing awful. I'm terrified of having to leave them or something happening to them. i even feel sick writing this down. How can I get a grip? What on earth would I say to the Dr?
