Back when I was much younger I had issues eating most things and dealt with stomach issues most of the time. What helped me was taking a probiotic supplement. If the balance of your digestive system is off (which it most likely is considering the symptoms you're suffering), then adding probiotics to your diet can help heal that issue and allow you to eat more foods without any negative after-effects. I can't say for sure that it will fix the issue, but it's something I would recommend looking into. I hope you find a solution.Another morning of waking up and spending half an hour in the bathroom. I ****ing hate my stomach so much. I wish I knew what was causing this.
