I can't talk on Tess at all as only know of her from the Cosmo thing when it was trending.I guess it's hypocritical to criticise someone else's health when your own health is poor. I still can't advocate for Tess Holliday though, she's a bit morally bankrupt from what I've read.
I've always avoided her food videos, I'm 17 and only recovered (as much as you can recover) from an eating disorder a year or two ago, since which I've gone to the other side of the extreme. However, I'm not taking any life tips on "getting better" from Melanie Murphy.
Morally bankrupt you say? SHE HAS THAT IN COMMON WITH MELANIE
Ah I'm so sorry to hear that, I hope you are minding yourself well and reaching out to those who can help you xx
