Confused!

The festive season is just round the corner. It is a time for celebrations and parties but here I am tied up with completing my reasearch and coming up with a thesis. Could it be due to the tremendous stress? Loneliness? that I am suddenly missing home. And now I have become a very confused human. From feeling sad about having to leave Japan in 3 months time and also wanting to go back home now..... I am a very very confused soul.... ???????!!!!!!!
