Not me thinking about how as a kid, I would get stomach aches in the morning a lot, but learned to ignore it because my parents thought I was faking it, immediately followed by remembering the friend of mine who told me about how one of her anxiety symptoms is stomach pain
An anxiety disorder looks like going through airport security and seeing that there is a drug-sniffing dog and thinking to yourself "DO I have cocaine in my bag??" even though you've never actually seen cocaine in real life.
