Can you say:
This week is the last week I'm going to be here for a long time.
I'm trying to say: After this week I'm going to be gone for a year or so.
This is my last week [here] for about a year.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Why are you leaving?
It's winter break.
Your winter break lasts for a year? (I was trying to joke with emsr2d2.)
Haha. I dont know where I'm going yet. I'm thinking about studying abroad for the year 2015.
