While you are entirely correct that immediate withdrawal of benzos is life-threatening, the same is true for short-acting SSRIs/SNRIs.

For eg, when admitted to a psych ward, there are a handful of things that the hospital will continue giving to a patient and gradually taper. Benzos, SSRIs/SNRIs, anti-psychotics, anti-convulsants & alcohol.

I mention this just to urge folks not to go cold-turkey on SSRIs/SNRIs as it can be life-threatening.
