What do I do?

So my stomach hurts, a lot. My doctor only has me on the Amoxicilin and Omeprazole and not the other anibiotic last time because it made me sick the last time I took it. Not sure then if this will work to get rid of the H Pylori or not. Not sure what to do. I feel like this whole medical help thing has been very badly done. Mean while I am losing hours at work, making my family, friends and co-workers worry and feeling like crap all around. Not to mention my original problems seem to be getting worse. I am so confused now that I don't know what to do. Do I wait till next week to see the doctor I am scheduled to see? Do I go to the emergency room and demand help now? Do i call my doctor's office up and yell at them? I wish I knew what was best for me and my body. I keep trying to do the right thing so that I get better but nothing seems to help. No matter how much I sleep or how much I try to eat right my stomach still hurts, my doctors still treat me without testing me, they still put me off and they still don't call when they say they will, I keep making appointments and calling them, I keep being honest and actively trying to get help. I got nothing. I just don't know what to do anymore and no one seems to have answers. And of course, the more no one can answer me the more I wonder if something could be seriously wrong. I have been seeing doctors since the beginning of July and August will be over before I know it. I have been having symptoms since June. Something has got to change.
