I'm not killing myself with worry, but there are a few places a person can disappear easily. I'd bug my friend more, but she launches into a "let's have my brother's bitch of girlfriend deported" rant. Sigh.
I wasn't worried either, actually, because she often does disappearing acts - but never like this one. Her parents/sister haven't heard anything from her in over a month (her mother's the only one out of province) and neither have any of her surrogate parents/grandparents. All of her stuff was left at her apartment - including her cat - with her rent only paid up until the end of May. The roommate has now gotten rid of the cat, from what I've heard - not sure about the rest of the stuff. There's been no on-line activity and she hasn't contacted any of the organizations she belongs to...very unusual for her.
