@Sanguine It's not realistic to expect most people to sit through Dr Lucire's detailed and extremely well researched dissertation, but I'm going to Try here to boil it down to a very basic principle (by no means all inclusive, or 100% applicable to every patient).
A basic, very common, Adverse Reaction all SSRIs and Neuroleptics carry is a condition called Akathisia.
It's routinely ignored by prescribers or downplayed if it's even mentioned.
What warnings accompany it in the Label caution prescribers to be particularly watchful for it in the first few days/weeks of the patient's Initial exposure to the drug.
It's a psychological unease so upsetting that patients have described it as making them want to jump out of their skin, or claw it off to get away from it.
Since it's swept under the rug, the patient, being left in dark about it, mistakenly tries to quash it with an overdose of the offending drug which of course blows it into a truly unbearable internal hell.
And Wham, you have the explanation for the overwhelming preponderance of Suicides in new patients/teens, rather than Homicides from them.
