I've cut off 99% of the family and have never been happier. I'm only in contact with one aunt (dad's late brother's wife) and very low contact with my half sister.

My alcoholic bio mom claimed I tried to kill her by pushing her down some stairs (she fell down drunk) and everyone on her side of the family defended her. When I tried to explain what happened my cousin told me to stop hurting my mom and that I was no longer family. They've been spreading rumors about me to anyone who will listen. I'm done with all of those disgusting people on that side. My covert narcissist dad refused to take accountability for taking away my Christmas present without even asking if I had the item in question or not, he just claimed I did, though now I think it was just an excuse to not give me one. This wasn't the first time he did something like that, on one other occasion everyone but me got expensive presents, I didn't get a gift at all. I even gave him a list of stuff I actually needed well beforehand, cheap practical things. When confronted, he just screamed at me to "Let it go! Like the song!" And demanded that I respect him because he is my father. I realized he was a narcissist with anger issues and that he was either jealous of another gift I'd gotten or set the whole thing up to make his wife happy, as she loves seeing me unhappy. My grandmother is one of those who think my dad can do no wrong and worships him. She told me to not to talk back to my stepmom because she will hurt my dad, it was always okay if she hurt ME, but not her precious baby boy. It's her fault the way she is how he is, she always put him on a pedestal. His sisters might realize it but won't get involved. His brother would have stood up for me but he died. My malignant narcissist stepmom sent me a nasty text message claiming I made up my health issues for attention (they were all professionally diagnosed) and that I'm trying to kill my dad with stress and that I'm super greedy. (All I ever wanted was to be treated as well as the rest, no more and no less) I found out later she doesn't even value her own children and disowned one of them. I am done with those two and everyone who sucks up to them and thinks they can do no wrong. Ie most of them.

Yeah, my family sucks.
