First, get a new psychiatrist. This one isn't for anybody. For some people benzos despite being addictive and being very hard to stop taking etc. may be the only solution. A better solution because it's not addictive is to take an antidepressant; when they work they also work all the time, not just for a short time. But there's no guarantee they will work, they also have side effects, and they can also be very difficult to quit. You're already addicted to the benzos and everything bad they do is already going to happen to you, so for you there's no reason to try to avoid that obviously. Get a new psychiatrist. In the meantime, think about antidepressants and you do have to keep trying therapy and lifestyle changes that might make a difference long-term.
You say he wants you off benzos. What does your psychiatrist say he wants you to do?
