Criticisms often bother us when we suspect they might be true I find. Not at all saying that your boss was right, but a lot of people have 'imposter syndrome' so it can become a case of 'agh, my negative internal monologue has been confirmed by an outside source'.
Is your boss just a bit of a dick that a lot of people dislike? If other people like your work it's probably way more about him than you.
