Can anyone help ?

Thank you In advance for taking the time to read my question. I was diagnosed with stage 2.5 to 3 as they called it rectum cancer in November 2019 . I was told that I would need radiation and chemo, and Offcourse surgeries. They started giving me radiation treatments that was a living hell. After the radiation came the surgery and I had an ileostomy for 7 months during that time I went through chemo. To make a long story short. I had my reversal on September 28 2020, and no matter what I do I can not control my bowel movement. Im taking Imodium and meta mucil and I eat very clean but nothing is helping me anything or any advice will help tks
