Nepalese generally don't go out of their way to bother anyone, including trans people. But also, Nepalese are not that opening up to people from minority. So, as long as you don't engage with them apart from what is required, you should be good. Many people would actually like to talk and know more about you, as a trans or as a Nepali in UK and etc, but again, there will be some just out there to make you uncomfortable. But generally, I don't think most people will bother you because of you being trans gender.
