Diverticulitis - help

Hello, I have very recently been diagnosed with diverticulitis and have spent the last 3 days in hospital on IV antibiotics. I have been sent home today with oral antibiotics for another 7 days and then have to go back in 8 weeks for a flexible sigmoidoscopy. I have an abscess next to my bowel and a small tear in my bowel.

Has anyone else had the same or similar and made a full recovery without the need for surgery? I am terrified that it wont heal and it will end up in surgery and needing a colostomy bag.

Also any tips on what to eat now whilst i recover and after? I have googled and asked my consultant but i cannot get any specific answers and some information is conflicting. Also what is okay to drink? Before this happened I drank a lot of milk, will this still be okay or not? I know I’m to drink more water. I am so scared of eating or drinking something that is going to make it worse or prevent it from repairing itself.

Any experiences, advice or reassurance will be much appreciated, this is all very new to me and I feel like I’m having to come to terms with something that is going to change my life.

Thank you
