How can I find relief from recurring gut pain?

Hi Sir, kindly help me out to get out of this pain, confusion and frustration. I am Rohan from Pune. This is my Clinical summary -Rohan, a 29-year-old male, presented with chief complaints of reflux symptoms and severe abdominal pain persisting for the past 3 months.And episodes of diarrhea.Upon examination, his vital signs were stable. Diagnostic procedures, including gastroscopy and colonoscopy, were performed, leading to the diagnosis of a duodenal ulcer, pan gastritis and pathological findings of lymphocytic colitis. The treatment approach involved the administration of medications, as mentioned in the prescription, to manage the condition. Regular follow-up visits were recommended to monitor the progress and adjust the treatment regimen accordingly. After two and a half months of treatment, significant improvement was noted, with no abdominal pain reported, and the patient's overall well-being has improved. Consequently, the dosage of medications has been reduced. Continued monitoring and adherence to the prescribed treatment plan are necessary to ensure complete resolution of symptoms and prevent recurrence. This was my condition eight months ago. Right now I am very frustrated because of gut problem. It's paining even after following treatment and strict diet for eight months. I almost lost 8 kg. I went for second opinion(Leading Gastroentrologist in pune) . That doctor told me that your ulcers are healed completely.And lymphocytic colitis was misdiagnosed. Now It's a IBS that causing the pain and not colitis.He prescribed me Librax(Clinidium+chlorobenzodioxide) two times in a day along with Amixide h(chlorobenzodioxide +amitryptiline) . Whenever my gut starts paining I took it and pain goes away completely like that problem doesn't exist.I am very confused about this.Stomach pain goes away and comes back. About year ago this problem has started. And just took those above medicines to cope up with pain One more thing to add here is that I was diagnosed with GAD (generalized anxiety disorder) few years back. I was taking escitalopram( Lexapro 10 mg)on and off prescribed by psychiatrist.But My Gastroenterologist told me to stop using lexapro as it can cause ulcer. So I stopped using it completely since year. I want to get completely rid of these medicines and want to live normal life.
