Consider asking your doctor about propranolol.
It's a safe, non-addictive beta-blocker often used to treat high blood pressure, but it also eliminates the peripheral nervous system response to anxiety, the "fight-or-flight" adrenaline rush feeling: racing heart, shortness of breath, inability to concentrate, shaking, sweaty hands, blushing, etc.
It doesn't effect your mental anxiety, but it'll cut out all of the physical symptoms, which makes the mental anxiety much easier to control, without creating any sort of brain fog.
