nayajivan, that's very admirable of you to plan on going back to Nepal. let's keep the family issues aside, because I can't help with that and I don't want to infringe into your family related matters.
You said you want to go home and serve. But could you be more specific? 
- are you thinking short term (a few months) or long term (a year or more)?
- are you thinking about working in/near the valley or in remote areas?
- do you want to be involved with organizations or serve through your job?
- any specific plans/interests you have in your mind?

i wish every Nepali who comes to US or any other county to gain education or training were like you. on one hand there are people like you who seriously want to go back and work for Nepal despite their families' unhelpfulness and on the other hand there are people who turn their ears deaf to the cries of their families and stay here illegally or through asylum.
