My friend is cluelessly insensitive and it's making my ed worse. Anyone have a similar story?

My friend is a tik tok influencer and naturally super thin, I helped sign her up to modelling agencies and always look at opportunities this could get her. I recently told her about my ed and how much it affects me, I think she took it more as a joke because she replied "girl.. you just need to get off of social media"... whenever were on face time she body checks in crop tops and says how bloated she is, and sends me tik toks of skinny girls saying "omg tea" or yk just reposting pretty girls. Being this young and impressionable you can tell this is making me insecure and I spiral even more, she never calls me pretty unless I say something about how I feel ugly. It just feels like she's es not aware at all and instead of supporting me she just says "youre gonna fu*k up your body and then be even sadder" and yet influenced me to go back to ballet because I would be more "interesting" of a friend, and just makes random comments at my eating habits. Also ive told her numerous times that sending me those videos is in no way ever gonna help me feel better or better my habits yet she continues. How would one go about this? im not gonna cut her off because we are extremely close but I mean this is just kinda weird to me. any similar experineces?
