Hi Maven
What can I say? I've been there, the whole bag just as you describe it.
The irony with some of our OCD thoughts is not that they are irrational, but that they are very rational!
Most people are able to block out the frightening parts of reality and I think that OCD minds are just unable to block things out, it's as simple as that. The OCD mind is in a state of fear, and there is plenty to be afraid of in this world.
All we can do is gradually desensitize ourselves, by whatever means, so that we can put the realities to one side and live our lives.
Good post.
Peace.
