I met a relatively talented artist named FlygonPirate on DeviantART some years ago. She appears to be suffering severe trust and depression issues in the past few years, posting self-depreciating polls and reacting violently to every single person she meets, either by throwing a hissy fit or blocking/hiding their comments outright. When she decided she's done for good, she posted what might be her last journal.
I know she won't ever read this thread (nor will she bother to read my comments if I post it), but do you guys know what should I do to people like this if I face a situation like this in real life?
