if theres anyone that is close to you, really close to you. maybe a friend, they are good people to turn to. hopefully they know you really well, even if they dont know what went on and what is going on. talk to them a lot so that you are very comfortable being around them. if theres an arguement or disagreement starting to come up, dont back away from it. these arguements with close friends dont mean anything. your friend is still your friend no matter what you disagree on. they arent mad at you, and they still love you the same. maaybe after a while you'll be more used to people arguing against you. it doesnt always mean that they are mad at you.
a fight doesnt always mean hate or yelling or violence, usually, its just two people sharing two different opinions.
maybe this helped? idk, sorry if it couldn't. i really hope you are able to move past this fear
good luck!
