Stomach pains when stressed, what could it be?

I keep having horrible pain around my ribs, mostly when I'm stressed or frustrated. I had H.pylori back in August of last year, i went through treatment and the pains went away. Now they seem to be coming back, but mostly when I'm stressed, also had them around Thanksgiving and Christmas after eating holiday foods. The pains are about the same as when i had h.pylori, but they aren't constant like they were then. I know h.pylori can return, but i'm afraid that i waited too long to get treatment for it the first time and it may have caused an ulcer. So I'm just wondering if any of you have experience with this, or gastric ulcers, and can tell me what you think? Any help would be appreciated.
