I need some advice.

im 17, i finished school last year (i started school a year early) and i just feel lost. I didnt apply to any college/uni and im at home all day, i dont know what to do,i honestly feel lost and pathetic. i dont really know what i have to do and i dont have anyone in my life to help/ give me advice, i know its my own life but i need a sense of direction i guess, or even a little nudge in the right direction, maybe i just need some motivation, i dont really know, im just clueless at this point and i dont want to be the only failure in my family. Can anyone please give me any sort of advice?
