I'm thinking my anxiety is rearing its ugly head again, but I can't be sure. I just moved to Denver from NY and I was quite anxious prior to the move because when I visited I felt altitude sickness (headache, nausea, lightheadedness) and actually at a point I felt like I was going to faint. It got better during my visit when I drank more fluids, and everyone insisted that if I moved here I would acclimate eventually and it wouldn't be a problem. Before my move, I went to a bunch of doctors about my stomach issues (which have became so much worse in the past few months) who said my GERD was probably due to my anxiety, prescribed me some medications which seem to help a little. Now that I'm here, some days I feel fine, and other days I feel HORRIBLE. I'm starting to think it's my anxiety causing all of these physical illnesses (headache, nausea, and lightheaded) but I can't tell! I think I'm worrying when I go out that I will feel faint and it's making me feel even worse. Has anyone had similar issues, where their anxiety about feeling sick is actually making them feel worse? I'm starting to feel like I'm going crazy with all of these health problems and no one understands me. Any insight, or just someone who can relate would be much appreciated.
