re: Panic Attacks-Seeking Advice

See a psychologist specifically trained in CBT if it continues. Most individuals do not have repeat panic attacks after their first one. However, if it continues, it is one of the more highly treatable psychological problems for a clinician who knows what he's doing.

Xanax or other benzodiazepines can interfere with behavioral treatment of panic. They reinforce fear avoidance, can cause physiological dependence, and lose their effectiveness over time after you experience tolerance from repeated use. SSRI's don't typically interfere with CBT, but are not necessary in most situations.

Make sure you get a thorough medical workup (which I assume you got at the ER) before treating it as a purely psychological issue.
