Is it gerd???

Had heartburn and upper epigenetic pain for four weeks now. Woken at night by pain and almost what feels and sounds like fluid bubbling in Solar plexus area. Have to get up and drink mint or ginger tea.
Have doubled omprazole to 40mg so have despite a couple of days a week. Don't drink,smoke, an caffine, gluten and lactose free. No citrus food or spices.
Prior to this I did go on a bit of a chocolate rage for a couple of weeks as had lots of stress and anxiety. Am worried it's also cancer! Last scope early 2020 showed gastritis and gastric metaplashia.
Any suggestion gratefully received.

Had H . Pylori 2019 had antibiotics which killed my stomach had breath test 6 months after and had gone. Doc suggested double and it's prescription strength. Spoke with doc today and wants me to go back to 20mg a day as she said the 40 is not working to start citalopram 10mg to try and break the stress gut cycle and have bloods on Friday and will see me in 10 days for a face to face appointment in 10 days. Just feeling so tired and run down.😥
