Hey Matilda,
The suggestion I'm going to offer is very simplistic and you are welcome to disregard it as such... anyway...

When your mind turns toward those awful images... what do you do... do you try to resist them, shut them off, push them away? If so, you are feeding them your power. Have you tried to just let them go... stop fighting the visuals... and really let your imagination have a hey day... when they start... instead of cringing... really invite them in.... and pretend you are watching a movie... detached and just watching at the same time telling yourself these are only figments of your own powerful imagination... it is you that has the power to conjur them and you will not be scared, po'd or controlled by them.?

Sounds simple and silly... but it has worked for me and it helps. I've become a little more desensitized to them.

Just my 2 cents
