I think what might help is to accept that yes, you are falleable. As much as your mom or your boyfriend tells you that you're the living epitome of heaven on earth, you're not actually perfect. You do things that piss other people off (whether you know it or not), and all you can do is try to be a good person and when you get some constructive criticism, consider it. It's not meant to destroy you, and the more you hear it, the less sensitive you'll be.
