It may be anxiety. : If you feel uncomfortable when you notice someone sitting next to you, you may need to understand what the cause of the discomfort is. Sometimes high blood pressure ; thyroid conditions can cause anxiety. See your doctor for an evaluation and a possible referral to a mental health specialist. It may be necessary to differentiate anxiety from paranoia.
