My family acts like they hate me?

My family doesn't get along well either; everyone's cold to each other (minus my sister and myself). My friends don't even like coming over because of it. I think you should just ignore your brother, and not yell back at your parents because they have this "sense of entitlement". Like they believe it's okay to yell at you for any little thing, but if you raise your voice with them then they have the right to be angry and be even meaner. The best thing you can do is try and keep from yelling at them when they say something rude or hurtful. If you stay calm then you can avoid further damaging your relationship with them.
