Hi, I ve been lethargic, and tired all the time, and I ve been unable to put on weight. I m 164cm, 47kg, female, 18. I ve started having something like sleep paralysis , which has been really scary and strange. I end up really disoriented and weak when I walk some distance. I have no apetite, and I get off balance. I ve had fevers on and off, and vomitting in my mouth and a funny taste, but I m not sick. And I have bruises on my legs, but I haven t been doing anything to get them. I notice my heart rate is irregular, and I ve been woken up by abdominal pain a lot. All this is out of character, I want to be a healthy and good student, but haven t been able to be. What might be causing this? Will I need to see a doctor in person?
