Recently lost an old friend of mine to this. Healthy, early 30s. Every day they were posting selfies from a hospital bed, I reached out thinking they had cancer or something... they looked as bad as a living person can. No hyperbole I remember seeing my great grandma in the nursing home as a young kid and she looked better than this. They said it was just some bacterial thing but nothing was working.

Realized it had been weeks since I've heard from them, phone number was disconnected, had to log in to facebook to confirm the worst. RIP
