Imposter Syndrome?

I got into a school I had no business applying to but it still feel’s kinda fake :/. like im so below their lsat median but above their gpa median i was just so surprised when i got an acceptance email.

I kinda ruined myself because before i even did that my friend was talking about how her old roommate got a mistake acceptance email and they emailed her like an hour later saying sorry. i just keep thinking about that possibility. it kinda sucks because instead of being happy for myself i keep thinking about this. :/

I know i sound crazy but this is something that has been bothering me for a while. i got an acceptance email, an email welcome letter from the dean, and emails about student resources and housing but all of those are automatic arent they? i know i just gotta chill out🫠
