My doctor told me that eating ice constantly is a symptom of anemia. Also fatigue is a major symptom. You should probably go to your doctor.
I battled with anemia for about four/five years, and I tell you, it sucked. I felt so horrible, because it got so bad. I never went to school. I was so tired. All I did was sleep. I'm not sure what your iron count should be, but mine was 3, and my doctor was very concerned about me. I'm still anemic, but it's under control. I hope this doesn't scare you. Anemia is actually quite easy to control if you aren't the rebellious teen like I was, who hates pills and blood tests. Please see your doctor. I know anemia can cause other medical problems.
