I can absolutely appreciate where you are coming from and while I still think you need to find some way to work through these past experiences eventually, if you have no trust in the therapeutic process now, it probably won't do any good. I have known countless people who have experienced severe trauma and if they were not at a point where they were ready to address these experiences and trusted the process, it didn't help and could even make things worse.
If right now just getting your anxiety under control is what you need, then you should aggressively pursue that but please don't close yourself off to other options. There are anxiolytics available that are so much safer and carry less risks than benzodiazepines. Benzos are fantastic if used in a limited context and preferably as irregularly as possible so you avoid dependence (mentally and physically). They can complement other options such as buspirone, hydroxyzine, supplement regimes and so many other options.
I don't want you to be denied a treatment that works so well for you, I just would hate to see you become overly dependent on them and needlessly suffer down the road as a result.
If there is a large somatic component to the anxiety, beta blockers can be a fantastic option as well. They are a drug used for hypertension (high blood pressure), and when given to someone with anxiety, they shut off the physical symptoms - rapid heart-rate, sweating, shaking, etc. They are often used for performance anxiety and given that they have no abuse potential, doctors are much more amenable to prescribing them.
My main point through this is that I would hate to see you think that your only hope rests on something physicans may not want to prescribe and that there are LOTS of options that could be beneficial if you are willing to give them a try.
