[ Philosophy ] Open Question : How can I feel better and move on?

I had been studying in this city I hate for a year. I really wanted to do well in my exam and continue my studies in another country. My results disallowed me. I did not meet the foreign university's requirement by a few marks. I felt like my dream is crashed. I was really upset. I really let myself down. I had been struggling with my studies. in the end, did well in most subjects but one. I was speechless and I'm really disappointed. My next option is resit and do well in order to go to study there a year later. You know, just these few marks, things would be different. I find it really difficult to accept. 1 more year here, this thought is hurting me so much. I just completely let myself down. I will resit and go next year. One year... I wish it didn't happen. I wished I was well prepared. Right now. I need to move on but I find this hard as well. The thought keeps bothering me. Just few marks that ruined my goal/dream/plan.
