stupid school drama

so yesterday i totally flubbed this whole thing and im so overthinking it now like why did i even say that to [my friend] in the hall, was i just being petty? she asked if i could help her with something for class but idk we havent talked much lately because of some dumb fight we had over nothing, anyway i was like oh yeah great whatever ur asking me for favours now when u ignored me for a week. like why would i even think that itd be cool to say that out loud instead of just thinking it or something, really wish i could un-say stuff sometimes
