Stress certainly can cause hair loss. But, unfortunately so can illness. Go get a complete physical and blood work up. Find out what you can do to improve your sleep. Lack of sleep adds to your stress levels. You doctor can rule out illnesses that might also be causing the problem. Good Luck to you.
