Failed

You worked hard, or you would have failed.

You failed to wake Harry up.

If it had not been for your advice, I would have failed.

But for your help, I should have failed.

Without your assistance I would have failed.

If it had not been for your support, he would have failed in business.

If it were not for your help, I might have failed.

The reason why you failed is you did not try hard enough.

To my surprise, he has failed.

To my surprise, he failed the examination.
