Not a good friend

So my friend and I haven’t been talking lately and she might think I’m a bad friend but maybe I am. I’ve known her for 8 years and I’ve be her best friend for 4 years but I never liked her. I know that sounds really bad but we don’t share any interest and we don’t like the same things. She also always talks about how her life is so much worse than mine but it’s not because she over exaggerates everything and has parents who treat her well and don’t abuse her. But what’s really getting on my nerves is that she pretends to have major social anxiety and I know for a fact that she doesn’t. I don’t know what to do anymore because my patience is running out.
