NCLEX shut off at 85 today

Took my exam this morning and it shut off at 85. I left devastated thinking i absolutely failed miserably which is why it shut off. I did not think I was doing a good enough job for it to shut off at 85. I definitely felt prepared based on my uworld self assessments which were very constantly 75-79% in the very high and high passing range and listened to all Mark K. However the NCLEX was nothing like uworld. I felt like I drew a blank in there and knew absolutely nothing. I am sick to my stomach thinking I failed and do not know how I will mentally handle having to study again and wait to retest.
