I am not feeling well today and can not make it to class.

I am sorry but I am not feeling well today. I've been feeling dizzy since I got up. I went to school earlier hoping to feel better but the dizziness was still there. I Will not be in today but will make sure to arrange to make up the class with you. As soon as I feel better I will update you. Take care and again I am truly sorry and will make it up to you.
