There are success stories and failures, it depends on the person. The only cure now known is therapy with someone who specializes in the treatment of anxiety, such as CBT. Medication can help the symptoms, but can't cure the problem but if nothing else cures it medication is sometimes the best we can do. There are also natural ways to attempt to treat it, with plant remedies and amino acids and relaxation techniques. You should also, if you haven't done this already, see a doctor to eliminate all possible physiological causes of the problem, such as thyroid problems, other hormonal imbalances, blood sugar problems, etc. Good luck.
