i've been dealing with panic disorder; officially since 1976. i'm not sure there is just one singular cause of it period. it could be in your diet the air or even the water we drink. something triggers the flight / fight syndrome when there doesn't seem to be a reason for it. something is activating the adrenal glands. i do think stress; while it's hard to tell if you're under stress sometimes will cause the episodes or make them more intense. dealing with this issue; when you're new to it can cause much stress. i've been on benzodiazepines on and off since 1976. i’ve been more on meds over the last 25 years than off. your medication doses may need adjusted but anti depressants tend to give you a boost or make you feel weird; which can kick in an attack. try looking for more holistic approaches to feeling better like change your diet see it if helps. exercise try meditation reading or listening to your favorite music and breathing exercises help a lot. the medication; should you stay on it long will eventually need changes to another type or a higher dose. my panic was so bad; i had to open my own company to stay at home whenever i had to. it usually comes and goes; as they say waxes and wanes. usually it has other phobias which develop as well. you want to steer clear of people and places which you think cause the attacks. i don't know that they will ever disappear; however they should diminish in frequency and intensity. best of luck and work on your end helps a lot!
my primary doctor diagnosed me with anxiety disorder and prescribed xanax and zoloft. why do i still have panic attacks?
