Sometimes i think im going mad and im only 22. Please help im so scared?

get tested for celiac disease. Many many people are diagnosed with ibs and find out much later that they have celiac. it's an intolerance to gluten and it causes all kinds of health problems. Dizziness, headaches, anxiety are all related. I never had dizziness, but I had nausea, headaches, terrible anxiety, diarrhea, constipation, clumsiness that progressed, the list goes on and on. Make sure they test you for this!
