Agent, going home is never a bad idea though very few people in your situation (having just completed undergraduate education in US) do it. I don't think you would make a decision based on the advices you receive from this forum, you must have done your independent research to come to this conclusion. I admire you but people in Nepal will give you a weired look for going back and you should be ready to overcome all that. Also frustration will rule you for some time.
I don't know your financial situation or any other factors influencing your decision but given the situation in Nepal and considering you are still young, I would consider doing masters, work for sometime to make some money and then go back and do what you like to in Nepal. Again, you should make the decision based on your situation but if you do decide to go, go with your head high and proud for doing what you are doing.
Good luck with whatever you do !
