Those aren‘t just anxiety drugs. Lorazepam is a literal Benzo. Which means it literally depresses (ie. makes less active) your CNS (brain).

These drugs are highly addictive and tolerance forming. They‘re often prescribed for insomnia since they inhibit brain signalling.

Once your brain forms tolerance it increases excitatory signalling to „counter“ the drug. Which means if you abruptly stop, you get withdrawal. Your brain is „overactive“ you have seizures, loads of horrible symptoms, in some cases people die.

(Not trying to scare people, short term or sporadic use is actually decently safe, it‘s long term high dose use which is dangerous. But basically my point is „anxiety drug“ is underselling what this is.)
