This is basically the story of my mother.
About 15 years ago she was suffering from a panic disorder. Instead of trying to help her, her doctor prescribed a fairly high dose of benzodiazepines and be done with it.
These 'medicine' only made matters worse and changed her behavior radically. She became very closed up, never wanting to do anything, never leaving the house and always finding excuses not having to do anything. The stuff is also terrible for her memory, so she can't really remember anything since she has been taken these pills.
The worst part is that these medicine are highly addictive, and we have now passed to point where we had to accept that my mother will be on these pills for the rest of her life.
