Detailed Answer:
Hi! Welcome to Healthcaremagic. Thanks for sharing your concerns with us. We will try to help you in best way possible. First of all it's sad to know what you had been going through lately.

Based on the history you have shared, although mertazapine can even be used to treat the symptoms you have mentioned but at times stress or anxiety disorders for which it has been used in first place if still remain uncontrolled can trigger IBS symptoms or stress related gastric upsets.

Having said that, organic cause of these symptoms like in stomach related issues like Inflammation of stomach lining or gastritis as well as acid peptic disease or H.pylori infection should be ruled out. Complete blood counts to see haemoglobin as well as serology for H pylori may be needed before more aggressive work up like endoscopy. Liver functions and other baseline blood work up may also be needed.

Meanwhile antacids like omperazole before meals as well motility agents like itapride can be used. For fever or pain OTC analgesic like acetaminophen can be used. Wishing you a speedy recovery. Regards
