hit and run ocd will be the death of me

over 3 weeks ago now, i ran over a curb and convinced myself it was a person, because i was driving at night. by now, over 3 weeks, someone would’ve found something, but my brain will not let me believe that nothing happened, i keep thinking someone hasn’t found anything yet and i keep waiting for the day the police show up at my door. deep down, i know it didn’t happen, but the panic and anxiety in my body won’t rest. i feel like im getting triggered by how panicked i was when it first happened, HELP!! i want to think logically
