Just to update - she just sent me a text saying that her e-mail is working fine. That's it.
So I guess I'll see where that goes... I'm going to try and not worry about it. I've done all that I can for that family - much more than I am professionally obligated to, and even more than a friend is obligated to.. so at this point, while I feel horrible for the situation it leaves them in, it's a direct result of their poor choices (and perhaps my poor judgement in not terminating earlier). Thanks for the feedback!
