Is it wrong that I don't love or even like my sister?

I don't love my sister. I would never wish her harm, but if I could, I would wish for us not to be related. Is this cruel? Why must blood mean we have to be friends? Am I being unreasonable and is there a way to fix this? I do care about her, like I do every human being, but I'd rather be with my friends than be with her at all. It's not just a "teenager phase." I still love my mom and dad, and I'm very close to them. However, it's my sister I don't love or have ever really liked at all.
