I set up the wake up time on my galaxy note 2 clock and then...I was in hurry

For the first time, I wanted to use my galaxy note 2 as wake up clock, but it really gave me a headache!
It was midnight and  I set up a wakeup for 7:20 in the morning on it and then turned it off as I usually do with my Nokia cellphone...
But what startled me in the morning was the ringing of my private student. I picked up the phone and as nabbing[?] he asked if when I'll be there, because he was waiting for me about 15 minutes. I was really embarassed about it and apologized and canceled the class, then get up and went to the W.C for you know(sorry i dont know how i can write it politely ), then I shit! Oh, I missed my practice of daily yoga too, and I missed the breakfast as well.  Because I was in a hurry, I tripped and hit my knee to the floor it really aches from that day..

[Basically good.  Sounds like a really bad start to the day.  I've had days that started like that.  Remember that the pronoun 'I' is always capitalized.  A polite way of saying what you wanted to would be "I tended to business in the bathroom (or W.C.) or "I took care of business" or "I answered the call of Mother Nature".]
