Why would you think they're taking benzos on a thread about SSRIs?
Benzos and SSRIs are different things. The former is a CNS depressant that acts instantly. The latter builds up in your system over a month to increase the seretonin levels in your brain. They’re not really related except that someone with, e.g., anxiety might be prescribed both
Thankfully I wasn’t on Benzos, but my mother has been and they definitey can do a lot more harm than good.
