Where I live, you can certainly get in-patient treatment for benzo addiction. I'm not sure why it would be treated any differently than addiction to opiates or alcohol - it is a serious addiction, and unlike opiate withdrawal, unsupervised withdrawal from benzos can be physically dangerous. If I were you, I would make an effort to find an inpatient program for the detox piece of your recovery at the very least. You will feel much safer and more secure during your detox with readily available medical supervision and round the clock support.
