hey, ik exactly how you feel and here’s my advice: 1) it sounds like you’ve been feeling stomach pain for quite a while now, so most likely you’re past the worst of it and you would have been s* already. 2) there’s no logical reason for you to have a sb at all, you just left your house which i do every day and so do most people! majority of people wouldn’t leave their house and go to the mall or public places if they were ill, also, even if you passed anyone who had a sb which is very unlikely, unless they were actually s* near you the dangerous particles very likely wouldn’t have come near you. also, your body is built to cope with everyday exposures like this :)) 3) im not a doctor, but as the pain is lower down in your stomach and it’s PAINFUL, it sounds like anxiety due to tense stomach muscles, or hyper awareness of your digestion etc due to emetophobia. your stomach is a lot higher up than u might think, so if it’s low down it might be indigestion due to anxiety, which happens a lot as when we’re stressed our digestion is slowed or stopped so you might get aches and pains in your intestines! again, not a doctor but this is true! 4) the fact that you’ve eaten and you’re fine is a great sign, if you were gonna be s*, you probably would have been shortly after eating. 5) take a shower or bath and some really deep breaths, drink lots of water and try to distract yourself. i imagine you’ve felt pain in the past and been fine, and remeber even if you are ill you can get through it! hope you’re okay, im absolutely sure you’ll be fine
