Hemorrhoid or diverticulitis?

Hello all! This is my first support group ever, so be gentle... 🙂

I just recently got diagnosed with diverticulitis. From hearing stories from those who have it or know someone who does, I get the impression that my case is on the mild side, but I still don't really know how to manage this yet. I love beer, spicy food, red meat - all the good stuff that's supposed to be "bad". I've also been on an SSRI for almost 25 years, which I read can contribute to diverticulitis issues. I'm also naturally a high-stress person and, unfortunately, work in a very high stress job.

After my doctor visit where I got my diagnosis, I've started using Metamucil gummies with prebiotics; I'm trying to be more conscious of what I eat, particularly trying to choose chicken or fish over red meat when I can; and, I'm cutting back on alcohol consumption.

Any recommendations beyond what I've done to assist so that I don't have to give up these things altogether? I ate several spicy peppers, ate red meat, and drank beer over the weekend (Go Huskers!) and paid for it yesterday, with a slight gut ache and lots of trips to the bathroom.

Also, and I apologize for being graphic, but out of the 5 times I was on the toilet yesterday, 3 of the BMs were pretty bloody. The issue there is that I have had a hemorrhoid problem as well, including a transanal hemorrhoidal dearterialization procedure in January of this year. Now each time there's a bit of blood in there I am left wondering if it's due to a hemorrhoid issue or if it's diverticulitis. It did quit by the last one and no problems with that today, so I'd like to think something just irritated a hemorrhoid and caused it to bleed a bit. Anyone have anything on that specifically?

Thanks in advance to everyone for the advice.
