Self control?

How is this going to work??

I'm planning to attend to a job fair next week. And i know i'm gonna have to explain why i didn't graduate from college. A lot. And it's ok. It's not a secret. and i really thought i was over it. That i could talk about this subject without being emotional.

But obviously I'm not! Today i had this workshop in preparation to the job fair. We learned how to write good job applications. And i talked to the teachers afterwards, because i wanted to know how to explain in my CV why i didn't finish college. And of course I had to explain my situation first... and i couldn't help to shed a few small tears and my voice started quivering.

So how am i supposed to keep my self in control next week? I can't risk to start crying in front of a possible new employer!!

I don't know if i can do that.. but i have to! this job fair is my best opportunity to get a job.. fast! I need this to work!
