I know how you feel, i miss eating real food, it's nice to loose some weight, but a heavy price to pay by not enjoying anything i eat. I finished my treatment in June or so, and have been gradually feeling better, but I sure do miss eating the foods that I like. If it makes you feel any better, I have been able to add some of the foods i used to enjoy, in very small amounts back into my diet, but I had to change the recipe for most, it's still kind of bland, but i found that i had less trouble digesting green herbs, making some of my food taste a lot better.
The daily stress, I wish you well and hope that it works out for you, the only advice I have for that is to breath, try to calm yourself before dealing with stressful situations. Maybe talk to your doctor about it, they might have a simple solution, who knows.
I remember my doctor thought I was suffering from panic attacks when I first went to them about my health, because I was getting heart palpatations, and having trouble breathing, and a feeling of being completely overwhelmed... it was terrible, and the most unusual symptom I have ever had. That went away though, and I do feel a lot better...
I hope the h.pylori is all gone for you and that your recovery is quick. Good luck!
