Pylera, Omeprazole, H Pylori, Gastritis, GERD, Acid Reflux? Done with meds, still not feeling well.?

At first I had a mild stomach pain. Turned out I have H Pylori+Gastritis+GERD! The Dr prescribed me antibiotics but it didn't kill H Pylori. So Dr prescribed me Pylera. It had horrible side-effects. But I took it all for 10 days with Omeprazole and I am still taking Omeprazole (40mg/day). I still feel bad. Acid reflux bothers my throat and esophagus so much and I always feel nauseas, tired, dizzy, depressed... I didn't have these problems before taking the medications. Maybe I shouldn't have trusted the doctors and shouldn't have taken the meds. I think I have destroyed my healthy body with harsh medications. I feel so bad.....Did any body have the same experience?
