Is it really necessary to be so defensive about this? Mistakes are opportunities to learn. Don't waste the opportunity or you could end up making the same mistake again. Take it on chin. You messed up. You waded out into the deep water and got into trouble. When your drowning, do you refuse to believe you are drowning or do you call for help?

You are drowning in a sea of criticism. Ask for help on how you can do better in the future.
