Thank you very much for this! This is really great advice!!! I'm gonna start thinking about distraction, and also will start thinking that these feelings are going to fade away slowly...
I wasn't sure if you would find my advice helpful or not - I'm glad that you found some nugget you could take away.
I think we notice these types of thoughts because these thoughts are new to us, sort of like when we have a new car, we think about the car a lot, but once the car has been in our driveway for a month, the car is no longer new and novel. Once you've had the same repetitious thought several times it becomes less meaningful, like the car that has been in the garage for a month.
This reminds me of something that happened in an informal support group. A group of us (maybe five or eight persons) decided to take a walk of several blocks, nothing too taxing for most of us at the time. Someone tripped and she let a few *$&$@@ words fly, then she kept shaking her head, like it upset her. Another person who had been sick much longer said something along the lines of "You'll get used to it, it's OK."
You might say to yourself "That's an interesting line of thought" when you have these thoughts, and then let them go if you can. Some thoughts may resurface.
