I don't mean to jump off the subject of this so, so sad post, but I have some input...maybe having to do with your other thread.

I'm not at all sure that you're describing OCD, thep. In my experience, OCD acts much more self-centered. You're describing some kind of intense compassion and empathy...the " get inside it and imagine what it's like". I do that, too. IF I stick a label on it, I'd call it strong anxiety and possibly edging into a negative hypomania. Not really OCD. And maybe it's not necessarily a diagnosable thing...maybe it's just called "being a very caring and sensitive person". I can't get the horror of the shooting out of my mind. I keep thinking and thinking about it...it's awful to feel so helpless, isn't it.
