So I am 19, I used to love food and eating. I have recently learned I am lactose intolerant and stay away from dairy but more recently everytime I smell food at all it immediately makes me nauseous and no longer hungry. I am 5'6" and only 110lbs, I am afraid to lose much more weight but I just don't eat anymore. It has really taken a toll on me because I live a very active lifestyle between 2 jobs and I have no energy. Thoughts or suggestions?
