Hi Bridget,
I started by postponing the thoughts - but as you say -the next (and final step) is to let them float around and ignore them. This is what my brilliant therapist (Morgan) told me last time I saw her. I can do this sometimes when I am really brave.
For instance, when I was standing on my drain a couple of weeks ago, I saw what I thought was a crack and the drain was wet. To my surpise, I told myself: 'well yes it could sewage you are standing on: SO WHAT.' I walked into my house with my shoes on and have been wearing them since.
So I think the answer is to say to your thoughts SO WHAT. After all, whatever the thoughts, deep down, we know perfectly well that they are untrue and it is just our OCD talking. I must try this more often as the voice of 'sad glad' is interfering far too much lately. Once we ignore the thoughts we get back our control and our OCD voice will slip into the background in favour of our strong sensible voice. Let's try together, Bridget.
Hope this helps
Best
Anne.
