Severe indegestion from most foods. Dunno what to do anymore

Getting severe pressure around my sternum after eating, I've had all the tests on my heart and they've come back all clear. This morning I had croissant with jam, bacon and 3 eggs scrambled in coconut oil and half an hour lately it feels like someone is pushing in the epigastric region and I can't catch a breath

Does this sound like ibs? Doctors keep saying reflux but I don't think I want to be on ppis as I've read about the damage they can do

Can anyone help me please it's ruining eating and life

UPDATE. Just tried apple cider vinegar in water and felt a lot better.. what could this be if that's rhe case?
