Opinions on Omeprazole withdrawal

I was prescribed 20mg daily of Omeprazole for acid reflux at night in August of 2024. For some background, I have a pretty significant vomiting phobia and generalized anxiety. I took the Omeprazole faithfully up until about four weeks ago with the only side effects being occasional urgent diarrhea when I ate particularly rich meals. I took famotidine prior to this and for some reason decided to switch. I took them together for one day, felt terrible, stopped the omeprazole the next day and continued taking the famotidine before bed. This takes us to two weeks ago. For three days straight I woke up with a horrible gnawing sensation in my stomach and nausea. Given my phobia this was causing panic attacks. Since then, I have had non-stop anxiety, chest and stomach pressure, a sore throat and cough, and no appetite for days. I first attributed this to my anxiety but I think I am actually experiencing rebound withdrawal. I am considering starting the omeprazole again for relief but so terrified to go through this again. I have been unable to work for days and have lost 15 pounds in these two weeks. On the other hand if I thought this may ease in another week or so I would consider staying off the omeprazole. Any constructive input or advice welcomed.
