You'll need a change of viewpoint on yourself otherwise this could be a self-fuelling loop. But you already know that and is not changing much, right

Got my line training extended from 25 hrs to 75 because of inadequate landings. I could not really see what was so terrible about them until they started getting markedly worse around the 55 hr mark, just as the check-ride approached, when I could not even achieve the performance which triggered the training extension in the first place.
There will be practical steps you can take, PM as you wish. No, not cold morning showers, neither more vegetables nor aerobic exercise....
