I've just been confirmed...

The junior Sous Chef told me that I've been confirmed!! What a short period of probation. I thought that probation should be at least 3 months. Hmm.. Means I'm good!!! And today, I've been working for 12 hours non-stop, coz I'd someone else job!!! Coz I didn't know that wasn't my job. Tired like hell and angry!!! Now the hard part....
I'm don't know how to tell to the Chefs that I'm leaving to US... Should I told them now, or shall I wait until October. I'm feeling guilty especially to Clay (the Jr Sous Chef)... I think he trusts me and thus giving the job to me straight away and to Chef Billy for taking and always concern about me (and to other staffs, he's the nice Chef). What should I do???
I really wanted to go to US for the experiences not the money. I really want to learn more and I hope to be in pastry kitchen. But come to think about it, my current job isn't my cup of tea, coz I really want to be a pastry chef!! I can't waste my time anymore... I'm getting older...
And I cut my both index fingers, my right middle finger (thanks to the pineapple!!!) and skin on both my palm peeling coz touching too much water!! I'm getting sleepy... Take my bath and ZzzZZzzZZ...
