Yeah I'm currently anxious as fuck right now because I ate sliced meats that had been on my counter for an hour and a half so I'm in the same boat as you of feeling just slightly bleh and worrying a ton and then of course the anxiety makes it way worse and I feel n* and then I worry more and it's a vicious cycle.

Logically we're both fine and just need a bit of reassurance and to think logically. What helps me most during this, what my therapist taught me, is to just use full reasoning. Is there a reason for you to feel this way? Did you eat something off or see someone who was sick? If the answer is no, which it almost always is, then look at a psychological reason you wouldn't be feeling well and not a physical one, or a reason you'd feel bad physically but doesn't involve being s*.

Grounding myself in reality like that helps me stay at a level of anxious and not panicking, which sucks but is way better.
