Symptoms?

Hi first thank u for reading this .... I am new to this I have never had acid reflux gerd issues before ... I wanted to know if anyone has had anything similar to this .... I have suffered with anxiety my whole life so this scared me quite a lot the past month or so everytime I eat I was having really bad stomach pains even laying down sometimes it hurt to even move so I would just lay in bed bad gas constipation etc .... well one night I was laying down awoke around two am and stood up I felt this horrible feeling of nausea like I was going to throw up my mouth tasted so sour and everything smelled weird I stood there for a second and moved around a little took my dog out and all of a sudden I felt like I was going to throw up I got light headed chest pains my arms and legs went weak and had such a bad feeling in my stomach I went to the dr he said I have acid reflux but is that normal for it to feel that scary that's never Happened so I just want someone's opinion if it was acid reflux or just my anxiety because sometimes I feel that way with a panic attack

They did X-rays and another kind of test I forget what it was I got two prescriptions one for Prilosec and another antacid in liquid form blood work was all fine
