Well,it depends on what you expect here and how you take the things,as far as your query about life being miserable.The situation when you are a student in Nepal or US is very different.Most of the students in Nepal don't work and whereas most of the students here work for different reasons.People have great respect for those who work(or don't care what you work for your living except ...).Even if you get tuition waiver,you have to work for your other....and most importantly,it is not the money that matters for you,you will get very important work experiences and so many...,if you work here.It is not only the international students who work here,most of Americans do work for different reasons. If your parents are wealthy enough,you doNOT have to work.I have seen some Nepalese students who don't work here are supported by their miliionaire or billionaire(NRs.) parents.But,I think they miss many .....which canNOT be bought by money.After all,work experience of any kind matters much here. Life could be miserable in the sense you miss many things here.you are 'loved one'for your parents,but nobody would be for you here.Your mom should be very aware on what you eat or do Not eat;who cares here unless you get some friendly and helpful ones.You most probably get friends from Nepal who could help you. You can compare your life with US citizen who work for many hours.Everybody works here,so why not you .......? Once you get in here,you will simply enjoy it.I am NOT lying. One difference is quite visible:you might have burden of study and exams throughout the semester,unlike what you are used to in Nepal where you have to care final exam only. By the way,I am NOT an UG student,I observe many UG students and their life styles.I they feel great here.
