Hello @marshelly1 and welcome to Mayo Clinic Connect. I am sorry to hear that you are bothered by diverticulitis. This is a painful disorder to have to deal with. I am somewhat surprised that your doctor has not given you much help in preventing these flare-ups.

Keeping constipation at-bay is very important to prevent more flare-ups. The diet during a flare-up should be rather low in fiber, often a liquid and/or soft diet, along with prescription anti-biotics. Bed rest will also help you at this time. However, once you are over the flare-up then it is a good idea to keep fiber in your diet in order to prevent constipation. It is a good idea to find a chart of foods high in fiber and start to very slowly adding fiber to your diet. Keep well hydrated include a lot of liquids (non-caffeinated). Often there will be certain foods that you may find will trigger a flare-up. You might consider keeping a journal of foods and see if there are any that are triggers. Often the use of fiber supplements (like Metamucil) and stool softeners (like Miralax) can also be added to your high fiber diet.

Here is some information from Mayo Clinic's website about diverticulitis, https://www.mayoclinic.org/diseases-conditions/diverticulitis/symptoms-causes/syc-20371758. I would encourage you to read the article. It talks about fiber, exercise, liquids, etc.

You don't mention how many diverticulitis events you have had? I'm wondering how they have been treated.

I would like to hear from you again. Will you post with a little more information?
