This is why your psychiatrist wants to see you. For one, Prozac, while being the easiest ssri to come off of, isn't the best for anxiety because it tends to be stimulating. Great place to start because it's got a reputation for being easier to come off of, but not so great for results. If it isn't working, that's what you need to discuss with your doc. If you want to go without meds, then you need to do therapy, which you should be doing even if you're on meds.
