They're terrible for some people, but they work well for others. I don't think they should automatically be disregarded.
> In the worst case, they cause suicidal ideation
Is this actually true? My understanding is that people in severe depression can have suicidal ideation but not actually be able to put in the effort/energy needed to go through with it. SSRIs initially give you a little more boost in energy before the mood-lifting effects kick in. During that middle phase, we observer higher suicide rates because you've now enabled them to have effort to follow through with their suicidal ideas.
