Anyone else have an experience like this?

Hey. I’ve been diagnosed with IBS since I was 12 and have been experiencing extreme stomach pain with other symptoms since I was 4. It took forever with multiple tests done for them to decide on IBS. The thing is they found white foam and white blood cells all over my GI tract when I was little, and they only said IBS because they , and I quote, “don’t know what’s wrong and it’s time to give up.” I have since found no relief and have ended up in the er due to extreme pain and blood in my stool and vomit. Now I have to redo all my testing but I’m scared the new doctors will give up too. Has anyone else had an experience similar to this? 😭
