There probably is a fair amount of trolling going on too but I am also talking from direct experience, particularly recently when it has reached disproportionate levels.

I have been there too so I can empathise with the thought processes behind suicide. I have thought about jumping in front of a train (at that very same station) a few times in the past but thankfully I have always dissociated myself from the idea and thought logically about it. I guess that is the hardest thing to do though when you are intent and in that mindset.
