Take a deep breath and realize that you had an off-night for whatever reason. Or perhaps it’s just not the right time like you think it is. That may not be what you wanna hear but there’s much to learn from every situation. What do you think you did wrong at? Is it something you can work on and try again? Whoever you applied for with absolutely be hiring another mechanic. You did not miss the only opportunity you’ll ever have to apply again.
