harman-sounds like my son,it's so exhausting and heartbreaking.I sympathise.We've had these problems since sept(he's in year 1).He was being picked on ,and finally the school seem to be dealing with it,and he has been a bit better recently.However,we are moving him to another school,as we don't really think the school he is in suits him that much.there are several children with real problems in his class,and it's so disruptive for the other children.If your dd is so upset,something is clearly not right,and you must push to find out.It took me taking him out of school for them to listen to us,and do something about it.good luck.
