Hello, I've been experiencing this extreme nausea every morning, and sometimes it sticks the whole day. I never vomit, but today this morning it was so bad that I went to the bathroom to vomit, but nothing came out. This all happened when I got some kind of virus that stuck the whole summer. This made me really stressed as school was around the corner, and I have some pretty intensive courses.  I've never had this before, I'm a very healthy guy. Before all this happened I used to workout 5-6 times a week. But when this happened I've been on and off boxing  since I just do not feel good at all. I've been described omeprazol but it isn't really working out at all. Everytime I eat, suddenly I just feel this stop in my stomach and nausea comes back. I just never feel 100% anymore, I barely feel 50%. I have this feeling that it's stress and anxiety from school, also that I just can't workout as much as I did before because of this nausea. Boxing has been a huge part of my life since I was a kid, I find peace when I box. And now I can't box as much anymore because of this constant nausea. I never had any health problems in my life, ever.

Any help is appreciated, thank you.
