This sounds like a type of social anxiety to me. I’m not a creative person but You could write about someone wanting to make friends with someone they see sitting along at lunch but they’re too shy to do it and they end up feeling guilty about it??? You can write about someone wanting to go out for a school play and because they’re too shy they don’t but they later feel guilty that they didn’t?? I have social anxiety so I feel guilty about being shy, if that helps at all.
