Hi, I have chronic fatigue syndrome and when I was 10 I got diagnosed with tacycardia. The tacycardia increased at night. Then I started to feel like everythings unreal at night and I felt like I was dieing.. I dident die but it felt like fainting. I'v been having this for one year then I dicied to tell my parents. My head started to hurt at night and I felt like vomiting. anyone know whats happening?
