Hi - I have very anxious 9 year old (girl). Elder sister and v.responsible/mature and has always been a bit of a worrier. Recently it has gotten worse and she gets really upset when one of us (me or husband) goes anywhere - starts crying, asks us how long we will be, where are we going. Thinks we won't come back or something will happen. She says she just can't help it but is becoming a nervous wreck. Any advice on helping her cope?!!!
