She's not coming back, I think it's very clear now. Her recently picking up studying journalism, plus now seeing the IG story she's posted a few hours ago, are pretty definite indicators.
I'm on my phone now so can't upload the story yet, but it's a clip from her match at Kremlin Cup 2017, and the caption reads: "2 years ago... Nobody knew then, that this would be my last match

".
This is not exactly a bombshell, but it's saddening. It makes me even sadder that we don't even know what has really happened... Probably something related to her health not allowing her to play professional tennis, but still, it would be nice to know.
Wishing her the best for the future :awww: :hug:
