Toxic Family✨

My sister is toxic. The only thing she talks about anymore is how many friends she has, parties, and skipping school. But we are so close, and I don’t want to tell her because I am so scared and I don’t know what I’m scared of, I just am. But she puts me down without even realizing it - when she brags about how cool she is, when I tell her that I don’t want to drink and she laughs. We barely have any fun conversations anymore because it always just comes back to her and it’s always all about her. What can I do? I hate this so much.
