now what

I am starting to get a little worried about myself. I have been trying to lose weight but in the past few days, I have not been watching what I eat. But, I have still lost weight. Almost 6 pounds in 3 days. No exercise either. Something is definitely up because that is not normal. I am also sick to my stomach all the time. Even if I take my acid reflux pills, I still get nauseous. That is just not normal.
