Dude, you are in a shitty spot but they did the right thing. They are trained to spot "drug seeking" behavior. And you display it. When my Doc refused to prescribe a certain med, saying he wanted the shrink to do it, he was passing me off for someone to make a judgement. He did not want to be blamed. The shrink talked to me for 3 sessions before he would change my meds. It's his job. And in those sessions, I had to convince him I was not "drug seeking".
You do this by researching a bunch of mental/pain killers, including narcs, benzos, miltown (carbox something), SNRIs, etc, creating a chart of pros and con, and asking him to try something new, so you can drop your benzo and narcotic usage. In my case, it was an SNRI with pain killing properties, ie: cymbalta or effexor. Once on THAT for a month, and still needing a benzo or narc or whatever, and they will give it to you if you are not an asshole about it.
Play the game, get what you want.
But you gotta play their game.
