But...on a scale of 1-10 (with 10 being completely obsessed)...i'm only about a 5 now, where as last week I was at around 8.5-9 and about to let it get worse.
So that's the good side of things i suppose.
My therapist had suggested I take his picture and superimpose it with an image of crossbones (representing poison) wither for real or just an image to picture in my head. It has helped me a great deal in letting go of my obessive thoughts when i recognize them.
