I used to get anxiety attacks most of my life. The last time i was hospitalized they became controlled somehow, maybe the new meds? I have no way to know but i am not giving up my meds as it's too scarry thinking of anxiety attacks. Also concerning your period, i also believe that could also be a a trigger. Hormones, etc.I had endromitriosis and had an operation to stop my period, am 52 and maybe that is also why i don't get anxiety attacks too?
