Problem

[lupinesque]

Dear Sinead,

Ugh, I know the experience and it is awful.  I was once so unable to 
get violent images from a book out of my head that I felt like I was 
going insane.  I thought I was never going to be able to stop them 
from hitting me out of the blue.  I'd second all the good advice about 
doing something soothing and distracting (replace the images with 
better ones), and just add this:  it does fade after a while.  Calvin 
and Hobbes (or whatever you find pleasant) + time, the best remedy for 
all sorts of things.

Hugs,
Amy
