Man chill out. You did ONE interview and your life is "from bad to worse" ??? Honestly, you could be in FAR worse shape. You should be THANKFUL you even got an interview. It didn't work out, that's too bad for them, but now you keep plugging along until you get that job.
Just because one place says it will be a year that's no reason to up and say "oh well next year will be a waste"
Come on dude, get positive. One interview is not enough to judge the rest of your life and career on. You are only 19. RELAX, SMILE AND Keep going to more interviews!
