Good one Secretkiller.

Dukhe, everyone goes thru that more or less. Don't forget what you came here for. Focus on study... Can't forget work. Keep a positive attitude. You will have friends. Once you finish study and find a decent job... Life will be a bit better. Long distances are not so easy to maintain. Try your best..don't be upset if it didn't work out as you wish.
In few years, you will be glad to know that it was just a phase of life...rather hard...but hey you will get over it.
It's all about realization. I spent some of my years here just like you said. Don't forget whatever you are going thru is momentary. Keep positive attitude. It makes life easier.
Like Secretkiller said you will be proud on your achievement. Cheers!
