Seeking support for recovery from diverticulitis surgery

I hope I am posting in the right section! I am almost four weeks in recovery from surgery to resection my colon because I have had so many diverticulitis flare ups. My last flare up started in June, 2022 and lasted until my surgery on Oct. 14. I had no choice but to have the surgery because I developed a stricture in my sigmoid colon. The surgery was supposed to be laparoscopic but ended up being open. It was seven hours. I was in the hospital for 11 days. Now home, I am still in some pain although the surgical site is healing well. My bowel function is a mess. Lots of gas too. I am getting no guidance on how to proceed or what to expect. I wonder how others have survived this. I am looking at a longer recovery because of the open surgery. I would love to avoid more problems in the future, and regain my health. I just turned 70. I don’t know anyone who has undergone this surgery and would like to talk to others who have!
