Have you had acid reflux for longer than 10 years?

Hi All,
As you know I suffer terrible health anxiety. I’m having terrible stomach issues yet again. Last night I had a severe bout of heart- burn that goes into my back but I’m not sure it’s acid reflux? I feel no burning but just pain, does anyone else get this? I’ve also had this on and off for 10 years, on and off losec and have months where I’m fine and can eat anything and then some months like now where I’m scared to eat! I don’t know what to eat anymore, no diets seem to work for me. Plus I’ve got that weird bubble back. I’m paranoid I’ve got stomach cancer as I know Gerd can cause this. Getting a gastroscopy soon but hugely paranoid about that and have been putting it off for months. I guess I’m wondering if anyone has suffered this for years and is still ok. I just want my gut back!! I want to eat nachos!
