Help! :(

Hello GERD Community i hope someone can give me some advice or at least make me feel less alone in this...
Brief(ish) history:
• Baby born October 2020. Shortness of breath for a few weeks following birth.
• December 2021 shortness of breath and globus sensation this time I saw gp (video call) who suggested it may be reflux and prescribed Omeprazole
• Omep triggered full on reflux into throat and heartburn. Switched to Pantoprazole
• Panto triggered more reflux and abdominal pains all over
• Switched to Lansoprazole
• Lansoprazole had reduced symptoms but not cleared them.
• Abdominal ultrasound showed fatty liver & hemangioma - to be reviewed in 3 months

Current situation is im taking Lansoprazole 30mg. Anything I eat or drink gives stomach pains and any fatty foods cause liver pain. Im going back to the GP on Wednesday im just at the end of my tether. I'm SO worried its cancer but no markers in bloods. Have been referred for gastroscopy but it will be months waiting for sure. I just don't know what to do. I have an 18month old and I'm so worried I might not see him grow up. I feel like doctor is fed up of seeing me. I've gone 35 years of my life with no medical conditions and suddenly this is happening to me and I just want to know what it is and why 😪 I'm scared to eat anything but empty stomach doesn't help either!
