My ex broke up with me the eve of the pivotal week of tests before exams. Via text. I was FLOORED. I was so angry and hurt. This was the week of tests just before the final hurdle to the final exams. Basically if you failed these tests no chance to pass the finals. 

I spent about an hour being really angry then I turned my phone off and focused. My friends said they had no idea how I was so calm but I had to extract my emotions from the situation so for a week I was an empty shell of myself. Once my tests were over I dealt with the chaos. It was intense.
