Hi emanuelabianca,
I also hate people fighting and quarreling. I find it very disturbing for my inner peace. But have you ever been into any sort of situation where people are arguing with you, literally your are being scolded or you are dealing with a very angry person? Do you feel threatened while someone is arguing with you in a loud voice? I don't know what you'd say but I'm really scared when someone does any of those activities with me. I feel insecure and really scared to confront others or stand up to someone's face and utter the righteous words. I don't know what to tell you regarding this but I hope you will be fine soon enough.
