Wow. All I can say is it amazing how many posts I have read regarding the same thoughts I have. I have never been diagnosed with pure o but it runs in the family and I have been battling with intrusive thoughts and panic attacks for a while. I've had everything from blasphemous relgious thoughts to thoughts of harming someone I love. Everytime I think them they totally freak me out. I was starting to get a grip on them and then my dad passed away recently. I'm having the same thoughts all over again and now they are causing me stress again. I just wish I could realize they are just thoughts and it doesn't mean I'm a bad person. I just hate thinking that way.
