I became friends with someone in psych ward who attempted jumping and survived because it wasn't nearly high enough. But he kept talking about his attempt, over and over again, this really messed with him.
He always explained how he did it in detail. He sat down at the edge, smoked weed while getting used to the view. Then closed his eyes and kept slowly rocking back and forth without opening his eyes again, and at some point he did it without even thinking about it..
He honestly made it sound so peaceful that I actually considered going this way for a long time
