I suffered from severe insomnia for 20 years. I divorced when I was 41 years old. After the divorce, I immigrated to the United States with my young daughter. At that time, I had to study at school during the day, do two jobs and take care of my daughter. So, I was exhausted, but couldn't sleep at night. I was nervous and irritable, had headaches and anxiety. My heart would suddenly beat very fast as if it was going to pop out, and sometimes it hurt. That pain was like being hit with an electric shock, which was very painful. Not only that, but when I combed my hair every morning, I found my hair fell out one by one, making me feel terrible.
