One of the commenters thinks this is essentially satire because she looks like when she dated the guy from DIIV, saying that it's a fake hickey. I think Sky was actually pissed when she got arrested for drugs because she lost jobs, so I do not think the new photos are referencing that. I don't think she's proud of that.
However, there was a period of time where she looked strung out or tired and the public would accuse her of using, to which Sky would claim that she's not putting out her album because she's sick and that she isn't on drugs. So when I say she looks sick or something medical I'm just trying to reiterate "well okay Sky says she's got a medical condition and it doesn't matter if it looks like drugs to us". People relapse, or "become ill again". 🤷♀️
