She does look "healthier" in that pic and it's definitely due to the tan, plus, looks like she actually applied some makeup.
That's why I don't get the 'She looks so ill and malnourished, she has an ED!' narrative. Literally, Tanya has always looked like death in her natural state. Always.
It's just she would fake-tan, and put on a full face of makeup (including bright lipsticks and false lashes), and curl her hair practically everyday, where now she apparently doesn't even own a hairbrush and seems to have forgotten what the word makeup even is. Not to mention... the fake blonde dye job just washes her out.
