“Cognitive Reappraisal” is the term for the technique in which you relabel the feelings your body is sending you towards similar feelings that are more productive for your situation. The common example of this is re-labeling the elevated pulse and sweaty palms you have as signs of excitement rather than signs of nervousness.
Note - the two feelings have to be similar enough. You can’t trick your mind while you’re exhausted by saying “Gee whizz I’m so full of energy”. Doing this doesn’t work. You miiight be able to say “alright I am satisfied”.
