There is a post from a few months ago that touched on the subject, but it didn't receive a very in-depth response. What did the civilians that lived through the bombings an invasion of Stalingrad do in day to day life? How did they gain access to food and water? Did they live in camps or the buildings that survived the bombings?
In the book LENINGRAD: TRAGEDY OF A CITY UNDER SIEGE 1941-44, the author described the food residents subsisted on: bread rations were adulterated with sawdust; pet owners swap pets so they don't have to eat their own cats and dogs; glue, cold cream, rats, leather etc were eaten; some even resorted to cannibalism. People stopped reporting deaths so they could get more food ration.
The book also mentioned a 14 year girl named Tanya Savicheva kept a brief diary where she recorded the death of members of her family:
“Grandma died on the 25th of January at 3 o’clock. 1942.”
“Leka died on the 17th of March at 5 in the morning. 1942.”
“Uncle Vasya died on the 13th of April at 2 in the afternoon. 1942.”
“Uncle Lyusha died on the 10th of May at 4 in the afternoon. 1942.”
“Mom died on the 13th of March at 7:30 in the morning. 1942”
“Everyone died. Only Tanya is left.”
One of her sister woke up everyday when it's still dark, works two shifts making mine cases and then donate blood. She died at the factory. Tanya herself helped digging trenches. Another sister was evacuated at the moment's notice and a brother left before the siege, they were the only two members in the family who survived.
