I have acute anxiety I always feel anxious. I always feel that I'm going to die anytime. And I have chest pain and neck pain. Went through all the tests all are cleared except vitamin d. I'm taking weekly once. Usually after having food I feel dizziness and as if something is going to happen to me. I feel my legs and hands are shaking. Went to lot many doctors but everyone said I'm having anxi6and nothing else. How should I overcome
