You really should see a doctor. I understand that you don't have insurance but there must be a way. Please do not diagnose yourself by using the internet that is the wrong way to go about this. First of all if you stop and think logically even doctors don't diagnose you without performing the proper tests. the doctor may request a simple breath test or a barrium xray amongst several other tests. If you have helicobacter pylori which is bacteria in your stomach the treatment would not be only antibiotic.
It takes a combination of three prescription drugs to get rid of bacteria, one antibiotic, one anti fungal medication, and one medication that would help with the lining of the stomach. So because you don't know what you have you may even get an antibiotic through the internet and spend your money for nothing and take unnecessary medication that will probably not work anyway. The internet is great for knowledge though it cannot diagnose you.
