Anxiety and adrenalin

Would like to know if anyone has experience with adrenalin surges?
All the doctors have told me I suffer from anxiety, and that my symptoms are just in my head,so I need to calm down.
I'm not an anxious person, so I went to a reflexologist, and she said she senses that I am suffering from adrenalin surges, but doesn't from where. Could be adrenals, or thyroid, or pituitary.
She recommends more treatments, but I would like to put it out there to you.
Thanks for any feedback.
