I have absolutely no idea what to eat, any advice would be so helpful

Hi! I'm relatively new here and I desperately need some advice. A few years ago I had a diverticulitis episode after I had tried IF, OMAD eating one big, low carb salad a day (ELAB, lots of ladies my age have had great success). I definitely lost weight but I guess my guts couldn't handle all the roughage? And so the diverticulitis. Then depression, because I couldn't do the thing I found that worked, I spiraled a little, covid, and here we are now. I decided around January to try a cooked version of what I was doing before, it was going well, I've lost about 40 lbs or so, my guts would start to hurt, I would fast a bit, it would get better, and then another really bad diverticulitis episode a month or so ago. The ER Dr told me liquid diet, then low residue diet, I was doing that, and ANOTHER really bad episode. I feel like I'm going crazy!

When I eat carbs, I want ALL THE CARBS. So low residue diet for me makes cravings come back, and sticking to my calories is SO HARD. I want veggies but now I'm so scared to eat any unless I cook them to death. I'm scared to eat meat. I'm scared to eat dairy. I don't know what to do at all.

I have an appt with a gastro Dr. Monday. I know none of y'all can give me medical advice or anything, but I'm wondering if any of y'all have been through anything similar? I'm scared of losing my progress, I hate being in pain, I'm not the type to feel hopeless about things but I kinda am starting to feel that way.

If this is the wrong forum to post in, please let me know!! And thank you for reading 🙂
