Thank you for posting this. I may show this to my girlfriend as she has chronic anxiety, panic attacks, and (since our apartment fire) PTSD. She and I both know the dangers involved in even the benign use of benzos and having a story of the dangers will help us keep the doses, and those dangers, in perspective. I'm sorry you had to go through such an ordeal and I wanted you to know that your story will help many people.
as an aside, the pharmaceutical industry is a legal drug racket to be wary of. Exercise, diet, and meditation are incredibly effective at relieving symptoms of anxiety... never rule them out of your day to day treatment.
It is funny you should mention to be wary of the pharmaceutical industry, and that your girlfriend has PTSD because this is a prime example of the dark nature of these companies:
MDMA has clinically shown to have a near 100% efficacy rate of CURING PTSD in one single clinical session, and is not any more neurotoxic than readily available medications and generally only needs 1 session... but why sell something that works the first time? The money is in the repeats, and the dependance.
Not a lot of scholarly articles on it, but there are at least 3 I know of and they were mind blowing. Basic concept is that MDMA is one of the only things that can quickly and safely cause behavior and fear extinction which is what CBT tries to do over long periods of time with less than stellar success rates. You should check it out.
I am short on time but here is one to look at http://www.maps.org/mdma/spain_MDMA_JOPD.pdf
However, the one I was referencing I will dig out for you and PM you should you desire.
