Could use some insight about a strange medical appointment

I saw a gastroenterologist for chronic constipation who was highly recommended by a friend. At my last colonoscopy I learned I have a redundant colon. The doctor kept discussing getting back to "normal" but I have literally never been "normal." They said I should not eat bread or gluten but I don't have celiac disease or any sensitivity. They also said pasta from the US was ultra processed--it is minimally processed, and said I should shop in stores where products are grown in Europe because they are far superior. They also discouraged organic quinoa. They recommended Benefiber and Miralax, Benefiber is highly process and has gluten and Miralax is petroleum based. They also prescribed Nortriptyline without revealing it was tricyclic antidepressant off label. They said to ignore the 3 pages of warnings that come with the prescription. I did not fill the prescription. They also recommended pelvic floor therapy but my issues are not with the lower bowel. No mention of the issue of a redundant colon was mentioned. They felt my stomach and said I was seriously constipated, but that was not true. I am still reeling for the bizarre visit. Has anyone had a similar experience?
