Hope you feel better: Panic attacks can last for several hours if left unabated. Ssri meds such as zoloft, celexa, Lexapro ; Paxil (paroxetine) can help for longterm tx of anxiety. Immediate relief may be obtained from benzodiazepine meds such as xanax, Ativan or valium. Try relaxation techniques e.g. Tai chi, mindfulness ; deep breathing. Attempt to lower stress. Get regular exercise. Cognitive-behavioral therapy can help.
