First, I want to acknowledge your situation so I don't want to belittle what you went through in any way, but I had a catastrophic series of events happen in my life almost 9 years ago, and Xanax was literally a life saver for me.
Taking the Xanax allowed to me relax enough to do the work to figure out how to relax naturally. Before the Xanax I was having crippling panic attacks 24/7.
My only point is, you're a data point of one, I'm a data point of one we both had very different experiences. I don't tell people to take, or not to take benzos when they ask me, I just give my objective experience and let them make their own decision.
