That reaction is understandable, but looking at the bench after every mistake gives the mistake a second effect.
Try to create a reset routine that happens before you check anyone else's reaction. Take one breath, get into your next position and identify the next simple job. The manager's decision is outside your control; the next action is not.
Also remember that coaches usually judge the response to an error as well as the error itself. A young player who makes a mistake and then continues asking for the ball can show more than one who spends ten minutes trying not to make another.
If you are genuinely unsure how mistakes affect your selection, ask the manager away from the match. That can remove some of the assumptions you are making in the moment.
One mistake should become information for the next action, not a prediction that your game is about to end.
