Brave usually feels awkward in the moment. Nobody feels like a hero while their knees shake.

Nobody feels heroic while their hands are shaking. From the inside, doing something hard is mostly awkwardness, a dry mouth and a strong wish to be somewhere else, which is why people who have done brave things often say it felt like nothing much. The feeling you are waiting for is not part of the equipment.

Stop using how you feel as the signal for whether to go. Use the plan instead, so if you said Tuesday, it happens Tuesday. Let the shaking carry on in the background while you get on with it.
