Can i still dissown my family even if i'm 26?

WTF if their your family they shouldn't even think of treating you like that. If they treat you like that than yeah it's okay to disown them just don't talk to them or treat them like family until they start to treat you like part of the family. If it helps I disown my family because they always tell me I'm worthless and sometimes my uncle hits me but I live my life like I'm fine and I don't talk to them or treat them like their my family just strangers.
