OOF that happened to me this one time during my third semester in my peds clinicals. Slept through my alarm and woke up when my friend called me asking me if I was in the parking deck of the hospital. I sh*t you not I screamed and called my preceptor while I was changing and told her that I'd drive as fast as I could together, resulting in me getting to the floor at 7:30am instead of 6:45am. During my final review I got an unsatisfactory for professionalism because of it, but I still passed and now I'm starting my nurse residency next month. Although, I'm now paranoid about waking up early in the morning so I just end up staying up really late and sleeping a really shallow sleep with ten alarms set at most an hour early. Thank god I'm gonna be night shift.
This is just a short blip that will most likely just blow over, I hope that you're not beating yourself too hard over it.
