Stomach issues

[ThatxBritishxBoy]

I'm unsure whether my problem is based off stress/anxiety or something else, but ever since May when i had my Year 2 exams, -I'm 20 years old- I started feeling sick, it got so bad that for two days straight, i threw up after every meal i had, including water. I had to postpone one of my exams because of this, I had blood tests done twice, they all came out normal, I'm on Omneprazole & Metaclopramide regularly, however have also had Prochlorperazine buccal tablets and Co-magaldrox in the past few months for a brief period of time.

The meds help to some extent, the doctor said i have Gastritis, and it comes and goes, In Late May i felt better, but then again in late June and July till now, i suddenly feel the urge to throw up, most of the time when i wake up, i feel nauseous and as soon as i eat, i feel really uneasy as if i'm about to throw up, I had an endoscopy on Thursday 24th Aug, and my report said that apart from a very large patent pylorus -which i shouldn't worry about- everything else was fine. I'm waiting for the pathlogy results, and have my ultrasound procedure on the 31st Aug.

I'm on the fence about what is causing me issues, because i can barely finish meals now, and prior to May, i was never stressed about exams, so i think stress/anxiety is having some issues with my health. Also, i try not to eat out anymore simply because i feel the urge to throw up whereever i eat, additionally, I feel better eating at night time ( 7pm+ ) than anytime else during the day, it may be because i sleep really late due to holidays or some other reason.

Thanks for reading this lengthy post, any feedback/reply/advice would be greatly appreciated.
