As someone who has been in the same situation (though in my case my friend survived), I am very sorry for your loss. I still have nightmares sometimes about that experience - hearing the authorities bark orders into the phone on one end, hearing her scream at me, calling me a "traitor" when she realized I'd divulged her plans that she told me in confidence[0]. I even remember the exact song that I had been playing in the background (to give background noise, so she wouldn't realize I was on the other line) - I haven't been able to listen to it since.

Back to the topic, though: I'm in the opposite situation. This former friend and I haven't spoken in many years (for unrelated reasons), and it would cause a lot of problems in our social networks if we reconnected. Still, every now and then (perhaps once a year or so), I am reminded of her and have the inclination to check in on her. We're not Facebook friends, but thanks to Twitter, her public blog, etc., it's easy for me to see that she's alive and well[1].

I'm not sure how I would react if I checked one day and found that she had passed on, whether by taking her own life[2], or from "natural" reasons. It would certainly be very difficult emotionally to handle seeing remnants of her life all across the Internet, almost all of which have been generated after the last time we spoke in person.

[0] I pride myself on my integrity in general, but I don't regret my actions here. (She apologized later, for what it's worth).

[1] for some definition of "well".

[2] given the aforementioned history, there is a non-zero chance of this
