Sorry to hear.
The bad part is that image is now seared into your conscious and subconscious mind. Even when it fades from the conscious, the subconscious could bring it back at a moment's notice. Often in the worst of circumstances, such as a business meeting or an intimate moment with someone, or going to Wal Mart. No one knows what triggers it. I've heard of some results with electro shock therapy.
The good part is, well, there is no good part.
