saami: it seems like you are one of those guys who tries to come to States but gets rejected by the embassy several times. i visited nepal last year after being to used to American life for quite a while. well, it was hard at first. everything looked dirty and small. i was  scared to even ride on bus, let alone driving myself. but after 2-3 days, everything was back to normal - just like it was before i left for US. i agree that living conditions in Nepal are not so good from many different angles, but it's not as bad as you are trying to show.
come to the states and try living here like many Nepali bros and sissies are doing - you'll shit in your pants! 
america is not the america you guys have picture of in your mind. and in mba bro's case, it's a lot better for him in Nepal than here. maybe your life is not as good as other's and you are complaining here on sajha.
honestly speaking, when i read your post, the first thing that came in my mind was, "what a pathetic looser, can't even cope with normal daily challenges. how would this guy feel if he had to work in gas station 60+ hours a week at minimum wage and cover all expenses and at the same time manage to take care of studies and his health."
be content with what you have, and and live a happy life. you are responsible for whatever condition you are in, not Nepal. if you hate living there so much, why are you still there? pack your bags and get the hell out!

and all those "sheep" who are following this saami guy and saying things like, "there is no future in Nepal; why bother going back?" etc. there's a lot of reasons to go back and you'll do fine if you go back. all you need is guts to go back and try which majority of people lack. there are bad things back home, but no one is going to make things good for you. you better get there and start making changes. or stop complaining!
i admire mba's decision to go back. you'll do just fine, and live much happier and stressless life. good luck!
