carole, sometimes I read or view pictures of animal cruelty and it haunts me also. Some can handle it better than others. Some people ask me how I can do it? I tell them, someone has to. Someone has to know what's happening to animals in this world and pass the word along and hopefully open many more eyes and ears to it. I know who I can mention things to and who I cannot. I wouldn't want to upset anyone who couldn't handle it.
For those who can't deal with it, I say avoid it at all costs. As for getting it out of your mind, that's hard but in time it will fade to where, at least, you aren't thinking of it all the time.
