I'm studying to be a Homeopathic Dr, so take this as you like...
ALL mood stabilizing drugs, anti depressants and anxiety meds are habit forming, basically since they override the natural pathways your body simply stops producing the hormones that naturally stabilize you and then you can't function without the drugs. This should always be kept in mind when one is deciding if to take the meds or not. They are very hard to get off of once you start.
Anxiety responds well to massage therapy, and nutrition (try supporting your adrenal gland which are responsible for those fight or flight responses) Herbal sedatives and of course homeopathic treatment can also help although you shouldn't try to do that without a trained practitioner. Naturopathic Doctors can offer many alternatives as well.
Ultimately anxiety is like a gaping wound and anti anxiety meds like a band aid, they don't address the root cause of the problem and will only cover it up for so long.
