Models when ill – when is it time to do thought work vs when is it time to rest?

I am recovering from a spider bite which caused excruciating nerve pain and arm paralysis. I am much better now and my arm mobility is almost back to before. My arm aches and I am feeling tired.

My mind tells me that I should do a model to “disappear” my tiredness as it the result of a thought rather than the circumstance.

Another part of me says, “hold on a minute you just need to rest!”

How do I deal with these two warring factions in my mind?

Thank you for your help.
