Basically I have been feeling really tired for a couple of years now. When it started I went to the doctors, had blood tests and it came back with a really low iron count. I was put on tablets and stuff, and my levels went back to normal. Now I m not only feeling tired, but I ve got a really sore throat and glands, and my throat is swelling up occasionally, I m getting really dizzy, and I m so tired that I can t last a whole day at school. I went to the doctors, and had tests for Glandular Fever, Iron levels, gluten intolerance, and a couple of other things, but they have all come back negative. I really want to know what is wrong with me. I am a 15 year old girl. : )
