Is it possible to be the only healthy, moral, sane person in a family full of?

dysfunctional, abusive, unhealthy people? I am the youngest in my family and I have issues with all of them. My parents are perverts to me, have been emotionally abusive for a lifetime, my brother molested me and is a vicious bully, my other brother says cruel jokes at my expense, my sister condescends to me, speaks over me to another person when I talk to her (she is 13 years older and I am 21)..All of these things have been unprovoked on my part but being the youngest in the family I have been scapegoated and blamed and bullied to evidently make themselves feel better in their own lives. They all act as though I have the problem. I am in the wrong for being upset with them. I am the abnormality, freak, weirdo, bully for not being made of stone?? They twist things so that it looks like I am immoral, wrong etc...Is it likely that they are all the same and I am different and this is a good thing? They justify and minimize and condone each others primitive behaviour and gang up on me (strength in numbers and all that?).
