Anxiety is stressing about interactions and how they’ll go. Worrying that you’ll upset someone or say something wrong, or just even not knowing what to say next in a conversation. Thinking that people will make fun of you or hate you for who you are. Potentially even avoiding such interactions to “prevent” these manufactured possibilities.

Irritation is more like “Holy shit this dude has been rambling about inane bullshit I don’t care about for the last 30 minutes and isn’t getting the hints I want him to stop and go away. Please just shut the fuck up already so I can go back to focusing on what I was doing”
