Celexa tends to be a better med generally for anxiety than Prozac because Prozac tends to be stimulating, though Prozac is considered an easier med to take and
especially to stop taking. If you quit Celexa cold
just switched to Prozac, you could be suffering from withdrawal, or it cold be side effects of Prozac, or it could be the problem I mentioned, that Prozac tends not to work as well when anxiety is the main problem, though for some it works fine. Lots to consider.
