I just ordered lunch from a local place I get food from all the time. While eating it I noticed it tasted strange, almost a bit fishy? It could literally be anything but now I can't stop wondering if my food was tampered with. The delivery driver seemed to give me a strange look when he dropped it off and idk why I can't stop fretting over it. 

It's been thirty minutes since I ate it and I don't feel sick. The bag was sealed with a sticker so tampering wouldn't have been that easy. Why does anxiety have to be like this?
