Is it normal to feel like nothing around me is real during an anxiety attack? my heart goes so fast and body burns up. am on effexor (venlafaxine). what to do?

Panic Attacks: Yes, "derealization" is perfectly normal during a panic attack, although people experience varying symptoms during panic. The best treatment is exposure therapy provided by a center that specializes in treating anxiety disorders. Most independent therapists who treat anxiety do not have this specialized training. You should also consult with your psychiatrist about your medication.
