Tips for stomach ulcers?

I’m pretty sure I have one. I have a constant burning feeling under my rib cage and above my belly button. Anatomically right where the stomach is.

I’m gassy all the time, and it hurts to eat ANYTHING. Just the burning...the only thing that feels good is ice cold water.

I just want to eat something that will soothe the burning. It’s been like this for days so I made a doctors appointment and I have all the OTC stomach meds but there’s gotta be something you can eat that’s easy on the ulcer or soothing other than water. I can’t live on Pepcid and water.
