If you're honestly trying to solve a problem, you should assume positive intent from the criticizers- they're on your side and just want the project as good as possible. Everyone makes mistakes, and it's great there are people there to catch them and glean experience from. Is it so critical that you're actually walking on the edge of a knife to keep your job? (If so, I'd probably look for something else- that's no way to live!)
