I'm not arguing that. I'm arguing why it occurs as it's a really interesting reason.
When you're super down in the dumps, you simply don't have energy for anything. Even thinking about suicide is a chore so you simply don't do it.
When you start on an anti-depressant, it doesn't literally cause to become more depressed or suicidal.It causes suicidal thoughts by giving you the energy to actually have difficult thoughts and actions - including suicidal thoughts.
