What to do I can't stand her narcissism anymore?

I have a friend I've known for years. She's has a huge ego. I believe she's insecure because her ego is so big.

She puts down other people too. Sometimes I get a text oh I feel fat n bloated today. Then I get texts I feel great and I'm beautiful today. I'm so skinny and my face is great I just want perfection.

She makes me want to vomit because she's getting worse as her business is starting to really flourish.

She is not perfection and her skinny ness is making her look gaunt in her face as she ages. How the hell do I handle this her? When she texts me how great she is I just don't reply
