I once had an experience of somebody telling me in chat they ODed (directed them to hospital). was in pretty crappy place myself and spend night feeling responsible.... the person was fine......
I consider myself pretty tough person.... (have a desperate need for things to be okay though) and it was a horrible, horrible experience for me. These situations are hard to handle and guilt can be pretty bad. Sometimes it can send one in downwards spiral....
plus, there are people who are attention seeking, even unintetionaly even... and how many of us are able to handle this without taking it too much on ourselves?
