My 11 yr old DD has just told me (sobbing) that for many months she has been having scary thoughts, such as: she is too scared to be in her bedroom on her own as she is convinced something will grab her ankles. She says it's getting so bad she even has these feelings while walking to school. Lots of other things too, such as not being able to get in the shower without first standing still for some minutes in case "something gets her", only feeling "safe" on the third stair etc etc. I have done my best to reassure her that everybody has scary thoughts sometimes, and to let me know as soon as it happens, and that it's just a phase. Can anyone give me any advice? Do I take her to the doctor? Is this type of anxiety common?
