Moving/ worried about being taken off meds



So I found out my wife has lost her job and I'm unemployed. I see a doctor now who I've been with for years who has prescribed me benzos. I fear that wherever we move that a new doctor would not keep me on my current dose.
I've been on them for 10+years and I'm at a very good, stable, point in my life.
Has anyone ever experienced this?
I don't want to go back to multiple, daily panic attacks.
