I agree with TheB. In my humble opinion, anxiety in general does not manifest itself consistently. Anxiety is the brain's flight or fight response that was built into us to keep us safe and to survive. The brain cannot sustain this state for a prolonged period, nor was it meant to. If you were placed in a situation requiring this sustained state such as in war or concentration survivor, your mind would go into a numb like state to protect itself. You would also develop malidaptive coping mechanisms such as task avoidance behaviors, PTSD, DID etc. I think a professional would be a great idea to get to the root of the matter so you can have a higher functioning and happier life.
