My blood sugar feels low when it is normal. what could be the cause of this?

You are feeling: A drop after means, which is what your body is supposed to do. You are probably overweight and Insulin resistant. The treatment is weight loss through diet and exercise. Don't treat the symptoms with food, it will only make it worse. Don't worry, no one has ever been harmed by these symptoms. By the way, no one can tell their blood sugar by how they feel, except at the extreme ends of the scale.
