I have some stomach problems. There is not about feeling pain, but more a stomach discomfort. Because of that I cannot eat, especially on mornings. I feel like having a stone in my stomach. I suspect that this is due to the stress. I started a very demanding internship three days ago. After this all my stomach disorder started. I am very stressed, cannot sleep well at night (I wake up during the night being afterward unable to fall asleep). I cannot eat normally as I feel like I am about to vomit or after meals I can have diarrhea.
P.S. I never had a good appetite, but now it is even worse. I am loosing weight fast. I was taking some drops for appetite for about a month and it was OK. Now even this doesn't help much. I was always underweight and now because of this stress stomach disorder I eat even less and as a result I loose weight.
