When it gets to the point of that, they probably wouldn't care. I hate to say that, I had an ex kill herself in her brothers truck with his gun while he was training to be a marine. She was fine the night before, we hung out, nothing was wrong, I was called the next day by multiple friends that she had done it. No rhyme or reason to it. Selfishness is what takes over and its too much to bear so whatever will make it easier is the only viable solution to them.
The sad part is most children anymore have so much given to them they don't even REALLY know what suffering is, but they have it SOOO bad. It makes me want to laugh, despite the incredible sadness behind it all. There is so much to be said about things and times like this, I'll simply leave it as you need to take this as a wake-up call, especially those that posted on her FB that they loved her and expected to see her later that week, or the next day. Yesterday is history, Tomorrow is a mystery, but Today is a gift, and that is why it is called the Present. Write that down, put it to action, enjoy those you STILL have around you, for tomorrow they may be gone
