I'd get a med review by a new psychiatrist or medical doc if it were me. On the affordability of meds thing, needymeds.org is a wonderful website that will search for all financial assistance programs for your medications. Usually the drug manufacturers have assistance programs for each med.
I took klonopin for anxiety when I was in grad school, about 10 years ago.. I honestly preferred the anxiety (hated that drug!). The doc weaned me off over a period of 2 days and I don't remember withdrawal symptoms, however it was all I was taking, and I was taking a low dose (as prescribed).
