Hello everyone I'm desperate

So basically I had surgery in February and after all these months I still suffer symptoms like poor digestion and burping, I feel like it's hard for me to burp now and I'm struggling with contractions to my diaphragm like I feel throwing with no nausea but of course I don't throw anything out my mouth now. So I don't know now if this is cause by lamictal since I'm bipolar and I take high dosage and it causes this effects or something or are symptoms that are remaining for the rest of my life. I talked to my doc but he told me to take meds and supplements and nothing helps. Wtf am I supposed to do, I'm suffering so much.
