Can't focus due to situationship
for context I was involved with someone where we started off as fun but I fell in love and i knew he didn't want a relationship but i thought I could change his mind about that . However recently i started having anxious thoughts about this whenever I sit to study ( i have very very important exams going on which I can't study for otherwise also really hard for me to just sit and study usually always find reasons to not study ) so I decided to confront him recently which ended with me stopping it because I hate uncertainty and i can't study like that . I was really sad yesterday but accepted it today and i really really need to get back to studying but i was looking at my textbook for 2 to 3 hours reading one line every 15min because i zone out every 2 seconds thinking about me , him analyzing stuff that happened, analyzing me etc etc and i can't stop , sometimes I am thinking about other things too but for the life of me I can't focus on studying (like the zone in which I can usually read and understand fast) and it makes me irritated and disturbed because I am moving so slowly but my exams is in 2 days ,p.s med student, i desperately need advice to get out of the this immediately. helppp
