I'm just asking out of curiosity: why do you think you care so much about the negative comments?

I am one of those people that shrug it off, and if I were to try to rationalize my emotional armor, I'd say that the places these matters of taste and disagreement come from, like psychologically, are often not you're own fault and wouldn't really be fixable even if you tried.

But, I wonder if that might be missing the mark. The futility of trying to appease people who are unappeasable might actually have nothing to do with it.
