Theres a storm in there

I think there may be something wrong with me. Every time i eat i get an upset stomach afterwards. As my friends may know, i have been trying for some time to return my body to a state of homeostasis by eating activia yogurt and taking fiber supplements. But now i never have an appetite and my stomach is always bloaty and irritated. And i can always here it churning.... and complaining. I can get super hungry and just look at food and it doesn't even look or sound good to me, but i eat it because i know i should and then my stomach hurts really bad afterwards. im getting tired of eating.
