My only sibling is toxic to me. I limit our interactions as much as possible. Every single conversation I try to have with her about anything at all, she turns it around and it's all about her. I can't finish a sentence without her interrupting. I don't even call her much because a 5 minute call turns into at least 30 minutes. She refuses to text. She always calls and most times I let it go to voice mail. No matter what it is, it's always 'important'. So I've set boundaries.
