> “Ignored people I knew from class instead of saying hi because I didn’t know for sure if they remembered me even though the class had only 10 people in it”

This amuses me because it’s the exact reverse of my anxiety. I’m pretty bad at remembering the identities of people I may have briefly interacted with a few times in a situation like class or work, so I’m afraid of the “person from class” remembering me and me not remembering them and being offended. Like, “How about that exam last week” and me being like, “uhhh do we have a class together?”
