Frustration abounds!

Okay finding out that I had diverticulitis was a relief! I can't tell you how many nights I woke up in severe pain and wondering what this was. I am glad I now know. However, what do I eat? All the things that are good for me diet wise are not good for the problems I am experiencing. I ate an apple two days ago and had a lot of pain a few hours later. Berries, nuts, whole grains, raw vegetables are all out of the question right now. I haven't lost any more weight. I think I need a nutritionist. It was easier to eat healthy when I could substitute it with a great piece of fruit or some crunch veggies. So to the three people who read my blog. Any ideas?
