Advice

So I am so tired all the time. My husband calls me lazy but it is not my fault. I called my doctor and she wants to see asap. I hate going to the doctor but because I have Hypoglycemia and I have Anemia and my blood levels are very low. She said it is a emergency because she is worried that my body is shutting down. I am very scared about this because I am only 30 and I do not know why this is happening.
