Recently, I have been obsessing what I had said to my husband about a particular topic, by doubting, that he has the wrong information.
In the beginning, when the thought came, the anxiety was very high, for the next few days.
But now I have been able to differentiate about what the rational reality is about.
I am just leaving the irrational doubt of OCD at its own place, and not arguing with it.
I think it seems to be working on the OCD.
Of course, OCD kept giving me more doubts, when it saw that it was not winning anymore.
But I tried to use the same approach of rational versus irrational.
I hope this technique helps.
