Get over it!!!!!!!!!!!!!!!

Just found out that he is going away for vacation for one week and I feel sad because I know I will miss him. And we are just friends that talk everyday thru IM but when we see each other, we barely speak.
Why do I have to find out today?When today is the busiest day and I need to concentrate 100% since no mistake can be made and error cannot be corrected.
I need to stop hanging out with him.
