Neplease accent is not as bad compared to other asians like china, japan, korea etc...or some of those eastern european countries....but i have seen eastern european catch up the the accent faster than nepalease. Some young nepali 18 - 19 who just arrive here tend to catch up faster than the 25s and up. More u talk more u learn. Dont be shy to ask. Ask ur friend a correct way to pronounce words. And ask them to correct u when u say things wrong. Most of the time ur frens will not correct u becuase they are afraid that u may think of them as a mean person. But if u practice enuff, u'll get better.
