Flatulence all day

I am a 38 male 175lbs 6'0 I am on Adderall and Zoloft as well as Kratom. My bowels are usually like clockwork, infact I cant remember the last time I had a bowel movement outside of the morning. I have severe anxiety social, general and health. Long story short I last march I worked myself up to think I had pancreatic cancer and was in urgent care 3 times in 1 week, when I went in the 3rd time they gave me a CT scan with contrast of my abdomen and pelvis, which came back clean except a polyp in the gallbladder measuring 6-8mm. My doctor insists I get a colonoscopy because they found blood in my stool through a FIT test. I had it scheduled for May and chicken out and rescheduled it again for June. I went thought with it and that also came back clean except for 1 polyp, that was pre-cancerous but not cancer, they also performed a upper endoscopy, and did biopsy of stomach, small intestine and throat, which all came back normal. They wanted me to bulk up my stools so they have me on a daily fiber supplement and also put me on an PPI for my stomach looked pretty beat up, no ulcers just a bit aggravated, they said probably from Asprin and Ibuprofen use which I use frequently. So they wanted an ultrasound to check on the gallbladder in which the ultrasound said 8mm and to check in another 6 months. My diet has been the same for years. I eat at 10am, 2pm and then at 6pm. I eat cereal with no milk and stuff like cliffbars, drink black coffee but just have 1 cup, then its water or an energy drink. For dinner it ranges to really anything, from pizza to chicken. Before I go to bed I drink prune juice to get my bowels a head start so that i can go to the bathroom between 630am and 8am. I been doing this for 3 years about, but for the past 3 days I been having very bad flatulence all day, just random build ups then boom, but I don't have to use the bathroom, and there is no pain. I know someone will say its the prune juice but i been doing this for so long, and usually after my morning bowel moment I am good the rest of the day, and I don't feel sick at all. It feels like maybe I could go to the bathroom but I tried and tried and nothing even tries to manifest down there. Just gas. Any advice or experiences are appreciated,
