anxiety
"I had a very alarming ADVERSE REACTION to Ativan (Lorazepam), that I never had with any other benzodiazepine, that I'd like to share. My doctor prescribed me 0.5mg of Ativan for my anxiety that I've had since a child. Within an hour of taking my first dose I began to experience SCARY hallucinations, delusions, and paranoia. This never happened whenever I took Xanax, Valium, or Klopin, so I don't know what made Ativan different. 
      Not only did Ativan increase my anxiety, but it also caused these disturbing adverse side effects! I personally did not have a good experience with this drug, and threw the rest away. Please be very careful with it!"
