What should I eat with gingivitis?

I have had gingivitis for about 4-5 days, and have been working on treating it, but I have one major problem: I can't eat solid food! Even softer food like mashed potatoes hurts to go down in my gums, whereas stuff I can somewhat sip, like applesauce, goes down fine. I know I can't just eat applesauce, so I need some help finding out foods and drinks I would be able to ingest that wouldn't further the gingivitis or hurt unbearably. Please help!
