I understand your struggle, but I really think working on it will improve things for you, it's not just to annoy you. I also understand it sucks to hear everyone telling you the same thing and getting downvoted for expressing yourself. But this may also happen at work later and have worse consequences for your career, so I really think you should get over your anger and work on it. Maybe try to find a specialist that may understand where you come from and help you adapt.
