I don't like to judge just solely on pictures and offer opinions that I cannot back up with hard evidence, but the new pictures she has, she is clearly on something. Looks like meth, because the look in her eyes, face, and emaciated body tell it all. Poor girl, she clearly has some troubles, and as fun as the SP scene can be, there are some that need to work to live, and she looks like she's working to support some addictions, and likely using to null some of the pain of having to forget what she's doing.
For her sake, I hope she cleans up and gets better.
