Yup, that's a proper fu. If I'm your coworker, I'm not positive you'll be there the next day. Or the next. My brother took a train exit. Traumatized a first time engineer, because a lot of people take the train exit, but it was his first run. Pieces of my brother were scattered for quite a way along the track.

If you're actively suicidal, I hope you look into whatever seems like it could help for you. There are things in life worth sticking around for.

If something needs said, something like, "Yeah, sometimes I get sad, and one of my coping mechanisms is dark humor. Don't worry, if I don't show up to work, it'll be because I got a better job that pays more, har har."
