Is my family toxic?

my family says i’m annoying cause problems and are the reason my mom and dad are dying is what they say at least it make me feel like a disease they show me affection rarely and i am a adopted child my aunt and her husband take care of me cause my real parents couldn’t they always bring up my real father and his family my surname saying they are drunks and useless just like you and that they are worthless even tho most of that side of the family is wealthy and nice to me yet we are poor and i am always blamed for whenever problems happen i am kicked out of conversations and told to stop bugging them my real brother moved out and they used to blame him for everything and turned me against him he told me once he is gone they will do the same to me and once he moved out they have blamed me for everything and said stuff to me and degraded me such as fat, lazy, useless, annoying, needy i started working out to better myself maybe they would stop calling me that i lost a lot of weight and starved myself they still call me that i stopped talking for a while to stop being annoying but when i do they still say it i have ocd and adhd and they call me sometimes a retard for doing something like rearranging things cause of my ocd or doing something more than once they say why can’t u be normal and your weird i have hit the point of wanting to run away but can’t cause i don’t have a car they borrowed 3K from me and it took them months to give me it back and i had to beg it was my parents will money i brought a car and then my other brother well cousin blew it up and now i don’t have one and they tried to blame me i have just got to the point of i don’t want to go to school i want to drop out i have stopped caring and want to die is it me or is it them?
