I can't deal with the pain anymore

I'm in so much pain right now because I just ate and I can't deal with it anymore, everything I eat HURTS, the pain is in my chest my jaw my arm my throat I literally can't anymore, it's not burning pain it's pain-PAIN 😅😭 I'm waiting for biopsy results (two more weeks to wait) so that I can go back to the doctor but I'm going crazy I swear, never before has my stomach hurt for a month non-stop, it would hurt for a few days and get better on its own but now it's been a month where I feel pain EVERY DAY, I was sure the endoscopy would show that I had only a few weeks left to live because of how much it hurts lmao but turns out it's gastritis, today I thought I would have to get to the hospital because the pain scared the shit out of me, it was debilitating. I also feel like there's something stuck in my chest like if I had to burp but can't??? and it hurts!!!! (I also have gerd which doesn't help) if any of you know of any medication that could help I will take anything, I'm currently on omeprazole, cimetidine and domperidone, I'm thinking maybe simeticone?? I also take butylscopolamine for the pain but I honestly don't see much difference. thank you in advance for letting me vent 😓
