I'm severely underweight, anyone else have this problem?

Apart from the mental symptoms of anxiety, my major physical symptom is nausea. I have been nauseous my whole life. I have seen gastroenterologists. I have been tested (repeatedly) for celiac disease, lots of food allergies, H. pylori infection, lactose intolerance, you name it.

I wish I weighed 15 pounds more. I weighed 15 pounds more just a year ago, and I was in the "healthy" BMI category. I felt so much better.

Anyone else struggling to keep their weight up?

Yes, I'm underweight too. Pretty much been my whole life. I have a lot of nausea and I can't eat certain foods (dairy). I think I have IBS too. Nausea was one of my first anxiety symptoms. I feel like I eat enough, but I can't keep weight on me. Clonazepam has helped a little with my appetite and nausea. I drink a lot of ginger ale also.
