Hi,

I didn't read all replies. I talk work everyday in m head, despite that I've been on a sick leave for the last two months. At some point I realized that those conversation were harmful and that I should stop "participating" in them. If you want to stop those thoughts meditation will help. Not in the sense of sitting alone uninterrupted, but in the sense on not thinking. It takes a little bit of time to learn but it really helped me to deal with my work anxiety which was partially caused by the imaginary conversations.
