How much tenormin (atenolol) can i take to control severe anxiety?

Consult your doc: Atenolol is a 'cardioselective' beta-blocker. In layman's terms, it blocks the effects of adrenaline on the heart, and blunts the 'fight or flight' syndrome that anxiety-sufferers often needlessly find themselves in. This bodily response to anxiety (rapid heart rate, sweating) can further promote anxiety, a self-perpeuating cycle. Too high a dose can dangerously lower hr & bp, so consult your doc!
