People suffering from anxiety, panic, stress and depression should consult a specialist and only then should use the medicine, as there can be various reasons behind the disorder. Medicines used to cure such disorders are habit forming and should be used for small duration. As per my personal experience, I have used Xanax and it helped me in getting over my panic and anxiety disorder. Along with medicine, the concerned person should take a break from his/her regular schedule, go out and take good sleep.
