Averse to Feedback that Indicates my Needs Aren't Being Met

I find I'm often so averse to feedback that suggests my needs aren't being met that do my best to avoid the feedback... Instead of listening to the feedback, and doing what is necessary to address the needs to be met:

Me: If I floss, my gums will bleed... must avoid flossing! I don't want to know how bad things have gotten!

Me: If I exercise, it might indicate just how out of shape I have become... Must avoid all exercise at all cost, showing how much fitness I have lost!!!!
