Help about my future life?

i'm currently in third year college and i'm taking up nursing. i was supposed to graduate this year, but i stopped for one year. so now i'm bored. and as time pes by, my academic performance is getting worse. i don't even know if i still wanna do this, if i still wanted to be a nurse. and everytime i am in our 8 hour duties, i feel so sick and fed up and irritated. caz i'm not just into it. the whole field is really killing me. i want to shift to a new course, maybe HRM or anything that i want and i could do in my abilities. but i'm also thinking about the years i've spent and maybe "wasted" on this course.. and i've just one year left to graduate, which i'm not even sure if i could make it, caz i'm really lazy already. i don't even study anymore. please help me decide on what to do with my life.. i don't wanna end up flipping burgers on my future life...
