Yes I'm doing all of that but nothing is helping or stopping this horrendous feeling.
First, you have no idea if you're having adrenaline surges or not -- adrenaline is a real substance, not a metaphor. You're feeling anxious. The anxiety caused your phobia, not the other way around. Are you seeing a psychologist who specializes in anxiety treatment? Are you doing any relaxation techniques such as exercise, yoga, meditation, etc.? (A psychologist who specializes in anxiety treatment can teach you these, or you can learn them on your own).
